Latest / Stuff You Should Know / Noise Pollution: Arrrgh!
Transcript
- 0:01Speaker 1: Welcome to Stuff you Should Know, a production of I
- 0:04Speaker 1: Heart Radio. Hey, and welcome to the podcast. I'm Josh Clark,
- 0:13Speaker 1: and there's Charles W Chuck Bryant, and there's Jerry over there,
- 0:16Speaker 1: and this is stuff you should know. Can I tell
- 0:21Speaker 1: people what just happened? Sure? After what going on? Fourteen
- 0:26Speaker 1: years coming up? Yeah? And I guess in April Jerry
- 0:30Speaker 1: hit record and you went, hey, everybody, Wait, I've been
- 0:36Speaker 1: having a lot of trouble with my brain lately. I
- 0:38Speaker 1: think I'm just hey, I think you're doing great. I
- 0:41Speaker 1: don't know if I told you, thank you. I think
- 0:43Speaker 1: you're doing great too. Um, I don't know if I
- 0:45Speaker 1: told you that I had trouble remembering how to um
- 0:49Speaker 1: what six plus seven added together to the other day?
- 0:53Speaker 1: That sounds familiar? That really bother? Yeah, and that's like
- 0:58Speaker 1: my favorite number, and it's like I just couldn't do it.
- 1:02Speaker 1: I was putting my daughter to bed the other night,
- 1:04Speaker 1: and as she was going to sleep, literally falling asleep, daddy,
- 1:09Speaker 1: what's four plus four? Eight? Was six plus two? It's
- 1:14Speaker 1: also eight? Okay. She's learning math, and you know that
- 1:20Speaker 1: first stuff you learn is literally just that simple addition,
- 1:23Speaker 1: and it's just funny to think about, like, wow, that's
- 1:25Speaker 1: what's on her mind right now. Yeah, but also she's
- 1:28Speaker 1: learning acceptance too, just unquestioning. Can I tell people how
- 1:34Speaker 1: you spelled this document that you sent my way for
- 1:38Speaker 1: this noise pollution episode? Sure? Boy, you're just playing it
- 1:42Speaker 1: all out there, aren't you. It was fun because it
- 1:45Speaker 1: looked like a heavy metal band. It was n O
- 1:48Speaker 1: I Z E p O I think it was p
- 1:52Speaker 1: O L l U s h U n Y and
- 1:57Speaker 1: looking at him and pay for I was like, oh, man,
- 1:59Speaker 1: that's that's a good bad band name. It is, like
- 2:02Speaker 1: that's a that's a good name for a made up
- 2:04Speaker 1: band in a movie like Wild Stallions. Yes, and yeah,
- 2:09Speaker 1: although that's tough to compete with, you know it is. Um.
- 2:13Speaker 1: I also think we should, uh, we should give a
- 2:16Speaker 1: little c o ay here. I think it's impossible for
- 2:21Speaker 1: you and I not to turn into old man complaining
- 2:25Speaker 1: about like loud music and loud mufflers and stuff in
- 2:28Speaker 1: this episode. So it's gonna happen. I think everybody who
- 2:31Speaker 1: knows us and saw the title of this one knew
- 2:33Speaker 1: it was going to happen. But let's just put it
- 2:35Speaker 1: on the table now. Well and It's also funny you
- 2:38Speaker 1: mentioned this because I did mention noise pollution. I introduced
- 2:41Speaker 1: that concept to my daughter the other day and said,
- 2:45Speaker 1: you know, she was like, well, what's that and I said, well,
- 2:47Speaker 1: it's it's as bad as trash on the road, but
- 2:50Speaker 1: it's noise that's doing it and you should be aware.
- 2:53Speaker 1: And she was like, okay, um. And I guess it
- 2:57Speaker 1: never occurred to me that like loud noises for kids,
- 3:00Speaker 1: unless it's something that really bothers them, it's just part
- 3:03Speaker 1: of life. Sure, it definitely seems to become more bothersome
- 3:08Speaker 1: the older you get. Absolutely. I think I don't know why,
- 3:12Speaker 1: but I'm going to hypothesize that it's because you grow
- 3:15Speaker 1: to learn that it doesn't have to be that way,
- 3:18Speaker 1: and if you come to really resent the things and
- 3:22Speaker 1: the people who are making it. So yeah, and I
- 3:25Speaker 1: think that's why people One reason people retire to the
- 3:30Speaker 1: country or something like that, if they've lived in the city,
- 3:32Speaker 1: their whole life just a little more tranquil, perhaps even
- 3:37Speaker 1: bucolic lifestyle quieter. And there's a lot of science behind
- 3:42Speaker 1: It's not just like oh, I don't want to hear
- 3:44Speaker 1: those noises. As you will see throughout this episode it
- 3:47Speaker 1: is it's bad for your health. Hey, speaking of retirement,
- 3:50Speaker 1: have you seen that documentary on the Villages? It is bonkers. Yeah,
- 3:57Speaker 1: I saw it um actually when I had COVID when
- 4:00Speaker 1: on a documentary binge, and that was one of them. Man,
- 4:02Speaker 1: it was like one of the most disturbing documentaries I've
- 4:05Speaker 1: ever seen, and I've seen like dear Zachary, and somehow
- 4:07Speaker 1: it was like up there with it. It was good
- 4:10Speaker 1: man that I mean, I don't want to give anything,
- 4:12Speaker 1: but the one guy that was you know, this sort
- 4:16Speaker 1: of discosta that was It's kind of funny at first,
- 4:21Speaker 1: but then that got really sad to a lot of
- 4:22Speaker 1: a lot of layers and all of it was incredibly
- 4:25Speaker 1: sad that it was highly recommended. Yeah, just bizarre, man.
- 4:29Speaker 1: And then I was watching the credits and I saw
- 4:31Speaker 1: Darren aaron Oski was an executive producer. I'm like, okay,
- 4:35Speaker 1: you go. Now, thing suddenly clicked a little more. I
- 4:38Speaker 1: thought a great idea for a movie would be a
- 4:40Speaker 1: setting like that. You couldn't call it that because it's
- 4:42Speaker 1: I'm sure proprietary, but the town said, yeah, a setting
- 4:46Speaker 1: just like that where they wake up one day and
- 4:49Speaker 1: there's been a murder and then like you know, col McLaughlin,
- 4:52Speaker 1: it's kind of a twin peaksy thing, you know, the
- 4:54Speaker 1: stranger from a strange land comes in to investigate a
- 4:56Speaker 1: murder in a very unlikely place and all the sort
- 4:59Speaker 1: of or does there I think that would be a
- 5:01Speaker 1: cool movie or TV show. Well, I mean that is
- 5:04Speaker 1: Twin Peaks basically, right, But you could if you said
- 5:07Speaker 1: it in a retirement community in Florida, people, you could
- 5:11Speaker 1: just walk away dust in your hands off, like job. Well,
- 5:14Speaker 1: there's plenty of things that have done this. It's not
- 5:16Speaker 1: just Twin Peaks, sure, I know, just nobody did it
- 5:18Speaker 1: better than Twin Peaks. I A um, alright, so noise pollution.
- 5:23Speaker 1: I think the fact of the podcast to me came
- 5:25Speaker 1: right up front, and that I never thought of the
- 5:27Speaker 1: fact that a decibel was a tenth of a bull
- 5:33Speaker 1: or a bell, which his name is DECI right there. Yeah,
- 5:36Speaker 1: I know, I've never thought of it either, because you
- 5:38Speaker 1: never hear of any other variation. It's like one decibel,
- 5:41Speaker 1: ten decibles, a hundred decibles, you know. Um. And apparently
- 5:45Speaker 1: a bowl or bell b E L is named after
- 5:48Speaker 1: Alexander Graham Bell too. I didn't know that either. And
- 5:51Speaker 1: the reason why we why a decibel is used, which
- 5:54Speaker 1: is one tenth of a bell um, is because a decibel,
- 6:01Speaker 1: a one tenth of a bell difference in sound is
- 6:04Speaker 1: the lowest, the smallest difference that humans can detect. So
- 6:10Speaker 1: we trade in decibles here on, and we trade in
- 6:15Speaker 1: an algorithm when we talked decibles, because it's one of
- 6:18Speaker 1: those weird things where it's not like a hundred decibles,
- 6:22Speaker 1: is it twice as loud as fifty decibles. It's spit
- 6:25Speaker 1: into an equation that's actually one dred thousand times as loud. Yeah,
- 6:29Speaker 1: So so like ten decibles, the difference between ten decibles
- 6:35Speaker 1: and twenty decibles is twenty decibles is ten times louder.
- 6:39Speaker 1: The difference between ten decibles and thirty decibles, thirty decibles
- 6:42Speaker 1: is a hundred times louder. It's logarithms and zero dbs
- 6:46Speaker 1: as we'll call them. That is the threshold of human
- 6:50Speaker 1: hearing period. And a hundred and forty decibels is about
- 6:54Speaker 1: where you can start to experience literal physical pain from
- 6:58Speaker 1: a sound. Yeah, I saw between a hundred and twenty
- 7:01Speaker 1: and a hundred and forty. Yeah, it ranges like uh,
- 7:05Speaker 1: I mean I've been to some loud concerts and small venues. Yeah,
- 7:10Speaker 1: Dinosaur Junior at Variety Theater was it for me. I
- 7:13Speaker 1: was just about to say, Dinosaur Junior, they're one of
- 7:15Speaker 1: the legendary loud bands. It was insane. It is super loud,
- 7:19Speaker 1: but it's not like I don't remember feeling pain, but
- 7:21Speaker 1: I do remember feeling discomforted a couple of these where
- 7:24Speaker 1: I was like, jeez, this is like I like my
- 7:26Speaker 1: music loud, but this is a little much. Dude. Yeah,
- 7:28Speaker 1: like I don't wear your plugs. I wore your plugs
- 7:31Speaker 1: in that. And I was like, I'm saving myself right now.
- 7:33Speaker 1: It was so loud, and I meant to say Variety
- 7:35Speaker 1: Playhouse is not Variety Theater. Yeah, because we played there before.
- 7:39Speaker 1: We don't want a dis no, I know you know that.
- 7:42Speaker 1: But all of this to say, um god bless Jay Mascus. Yeah, no,
- 7:46Speaker 1: it was great, but it was really loud. What about
- 7:49Speaker 1: this conversation that we're having. What is that? Well, it
- 7:52Speaker 1: depends a normal conversation something around sixty decibls. And I
- 7:57Speaker 1: saw that that's people standing about a meter apart um
- 8:01Speaker 1: speaking without raising their voices. That's sixty decibles right there.
- 8:04Speaker 1: For a reference, What about a car. Cars are about
- 8:08Speaker 1: ten times louder to ten hundred to a thousand times
- 8:11Speaker 1: louder than normal conversation, depending on the car of the truck,
- 8:15Speaker 1: between seventy and ninety deciples. What about an airplane, So
- 8:20Speaker 1: you would think, okay, a normal conversation is sixty decibles,
- 8:24Speaker 1: airplane being a hundred twenty desciples is twice as loud. No,
- 8:27Speaker 1: my friend, it's it's a hundred thousand times louder. An
- 8:36Speaker 1: airplane is a hundred thousand times louder than a normal
- 8:39Speaker 1: conversation if it reaches a hundred and twenty decibles. All right,
- 8:43Speaker 1: If you've ever been on a tarmac, uh like a
- 8:46Speaker 1: live tarmac and heard a plane kind of landing or
- 8:49Speaker 1: taking off, you that's just some loud stuff. Yes, and
- 8:52Speaker 1: that's why they wear those cans on their ears. Yeah,
- 8:55Speaker 1: they and they definitely should because we're starting to realize
- 8:57Speaker 1: that there's all sorts of hearing loss, sides of the
- 9:00Speaker 1: traditional ones that you can pick up on a regular
- 9:03Speaker 1: hearing test. There's something called hidden hearing loss that we're
- 9:05Speaker 1: just starting to get our mind around, where the structure
- 9:10Speaker 1: of your hearing apparatus in your ear, the little sillia
- 9:14Speaker 1: that's almost like a venus fly trap trigger hair, but
- 9:17Speaker 1: for sound instead. Um like, those things can be intact,
- 9:21Speaker 1: but the neurons that form the chain between your ear
- 9:25Speaker 1: and your brain can be permanently damaged so that the
- 9:29Speaker 1: sound that gets to your brain is garbled or or
- 9:33Speaker 1: partially missing. And that's a huge thing that can happen
- 9:36Speaker 1: at much lower intensity than than we understood before. And
- 9:39Speaker 1: speaking of intensity, I think we should say real quick,
- 9:42Speaker 1: a decibel to us humans, we we basically talk in
- 9:45Speaker 1: decibels as like a measure of volume, because that's what
- 9:49Speaker 1: it appears to like us, like an increase in decibels
- 9:52Speaker 1: is an increase in the volume of the sound. But
- 9:54Speaker 1: really what a decibels measuring is the intensity of the
- 9:58Speaker 1: disturbance of an air of the air that's something has made.
- 10:03Speaker 1: So if you're really close to that disturbance, it's going
- 10:05Speaker 1: to be a very intense exposure to your ear. If
- 10:08Speaker 1: you're further away, it's going to be a much less
- 10:11Speaker 1: intense intense exposure because it kind of dissipates over distances.
- 10:15Speaker 1: But to you, it's just registering is a difference in volume,
- 10:18Speaker 1: where really it's a difference in the intensity of the
- 10:21Speaker 1: wave that's being produced that's traveling through the air. That's right.
- 10:25Speaker 1: And uh, this is all sound. Yes, that's not noise.
- 10:29Speaker 1: Noise is different. Noise is what we're talking about. Mainly.
- 10:33Speaker 1: A noise is classified as unwanted sound. Yeah, that can
- 10:38Speaker 1: vary depending on who you are, obviously. Uh, you know,
- 10:42Speaker 1: the sound of your significant other's voice after forty years,
- 10:47Speaker 1: maybe noise to you asking for some tea. The sound
- 10:51Speaker 1: of a Harley Davidson motorcycle being rebbed up in front
- 10:55Speaker 1: of your house might be noise. Or those uh, those
- 10:58Speaker 1: blowers that used to hay until you love and use.
- 11:02Speaker 1: I still don't love it, and I went battery powered,
- 11:04Speaker 1: but it's still even while I'm using, I'm like, I'm
- 11:06Speaker 1: a terrible person. But you get it done quickly, probably right,
- 11:10Speaker 1: so quick, so quick. I'm like mincing and prancing, just
- 11:13Speaker 1: getting in ton Uh. And there's a lot of kinds
- 11:16Speaker 1: of different noise. Um. Sometimes, like let's say you work
- 11:21Speaker 1: in a in a machine shop or something and you
- 11:25Speaker 1: use a machine, like the the sound the machine makes
- 11:29Speaker 1: is like it's not necessary, but it's it's a byproduct. Uh,
- 11:34Speaker 1: it's a result of the machine. Working correctly. It's not like, well,
- 11:38Speaker 1: let's just make this thing loud. It's like, well, I'm
- 11:39Speaker 1: sorry that Jackammer is going to be loud, because that's
- 11:42Speaker 1: just the way it goes. My friends are are Jackammer.
- 11:44Speaker 1: Episode is fantastic. Um. So that sound isn't necessarily noise,
- 11:50Speaker 1: but the intensity and repetition of that sound makes it
- 11:53Speaker 1: becomes noise. Yeah. Yeah, it's an unwanted intensity, or it
- 11:57Speaker 1: can just the sound existing itself, like you're saying, like
- 12:00Speaker 1: a leafblower, just an unwanted existence of sound. So either way,
- 12:05Speaker 1: the operative thing is it's unwanted sound. That's the key, right. Yeah.
- 12:11Speaker 1: And and this is another cool fact of the episode
- 12:13Speaker 1: I think is that, uh they they think that as
- 12:16Speaker 1: late as through the nineteen forties and into nineteen fifty,
- 12:20Speaker 1: natural sounds were still the dominant sounds that you heard,
- 12:24Speaker 1: um and then things really changed. Yeah, because there's a
- 12:28Speaker 1: there's a big qualifier that a lot of researchers make
- 12:30Speaker 1: that and not everybody does, But that noise is by
- 12:34Speaker 1: definition human caused, like either we're yelling or whatever, um
- 12:40Speaker 1: or one of the machines that we've created is making noise.
- 12:43Speaker 1: But that you wouldn't say, like the sound of that
- 12:46Speaker 1: waterfall is noise. Like we don't think of like natural
- 12:49Speaker 1: sounds typically as noise. It's just sounds. And as we'll see,
- 12:53Speaker 1: it's probably because we have been living, like our species
- 12:58Speaker 1: has been living around those sounds and has definitively excluded
- 13:02Speaker 1: them as threatening, so that there they don't They don't
- 13:05Speaker 1: produce like an irritation in us. They just are sound,
- 13:10Speaker 1: almost regardless of how intense they are, right and that
- 13:15Speaker 1: and again that irritation is subjective because that rock concert
- 13:19Speaker 1: that I enjoy, someone else might call that noise. That uh,
- 13:23Speaker 1: that Space Shuttle launch that is super loud might be
- 13:27Speaker 1: noise to some people, but to others, you know, it's
- 13:30Speaker 1: the same sound, but they they don't think of it
- 13:33Speaker 1: as noise because they're excited and exhilarated in the moment
- 13:36Speaker 1: to see and hear that thing. Yeah. So you know
- 13:39Speaker 1: the other night, Uh, the inspiration for um crew came
- 13:44Speaker 1: back on the Dragon Capsule. Did you watch that? No?
- 13:47Speaker 1: Did you? Did you see it live? Uh? We didn't
- 13:49Speaker 1: see it because they splashed down in the Atlantic, but
- 13:52Speaker 1: we heard the sonic boom it made when it came
- 13:54Speaker 1: back into the atmosphere over Florida. It was a stounding
- 13:58Speaker 1: Did you see that sonic boom? No? I didn't. Oh,
- 14:01Speaker 1: it's really good. It starts off like, oh god, this
- 14:04Speaker 1: is not good. This is like a terrible corporate ad,
- 14:08Speaker 1: and then it really starts to find its feet. It's
- 14:11Speaker 1: it's crazy how it evolves over like just the first
- 14:13Speaker 1: couple episodes. I gotta see it. It's good. It's definitely
- 14:17Speaker 1: worth seeing. Um what other kinds of noise. You've got
- 14:20Speaker 1: industrial noise, which that's classified as kind of from the
- 14:24Speaker 1: beginning of the process all the way to the end
- 14:27Speaker 1: of any kind of industrial process, and that's basically called
- 14:31Speaker 1: continuous noise. Uh, from you know, raw materials all the
- 14:35Speaker 1: way to the to the end disposal of whatever byproducts
- 14:38Speaker 1: can usually cause a lot of racket. Yeah. So like
- 14:41Speaker 1: you know, like um, like a generator humming or something
- 14:44Speaker 1: like that. There's not a lot of variation in intensity.
- 14:46Speaker 1: It's basically this um or steam being released or even
- 14:52Speaker 1: like a rhythmic like um, like a like something being
- 14:57Speaker 1: like hammered, no, not hammered. That a difference that's called
- 15:00Speaker 1: the impulsive noise. But um, just something that doesn't really vary.
- 15:04Speaker 1: It's just kind of a monotonous sound. That's that's this
- 15:08Speaker 1: kind of a subcategory called continuous sound. And it just
- 15:11Speaker 1: so happens that most industrial processes are continuous in nature, right,
- 15:17Speaker 1: whereas a train going by your house, or a plane
- 15:20Speaker 1: flying or a car going by or a siren is intermittent. Yeah.
- 15:23Speaker 1: And then also you could probably say, like if you
- 15:26Speaker 1: held the trigger down on a backpack leafblower, um, which
- 15:30Speaker 1: again is the worst thing that anyone's ever invented, but
- 15:34Speaker 1: if you held it down, that would be a continuous
- 15:36Speaker 1: sound for the whole time it was going. But no
- 15:39Speaker 1: one does that ever. They just rev in this rhythmic
- 15:44Speaker 1: pattern that your brain is just just giving. It's all
- 15:48Speaker 1: to trying to try to find a pattern in. And
- 15:51Speaker 1: so you get worn out and irritated so quickly because
- 15:54Speaker 1: of those things, because they don't follow rhyme or reason.
- 15:56Speaker 1: And in conjunction with that, it's an intermittent sound, so,
- 16:01Speaker 1: which is, from what I can tell, one of the
- 16:02Speaker 1: worst sounds for us. Right. And then you've also got
- 16:05Speaker 1: community noise, which is just people noise. I think the
- 16:09Speaker 1: leafblowers are thrown into that lawnmowers. Uh. You know, if
- 16:14Speaker 1: you've got a festival in your neighborhood, or fireworks on
- 16:18Speaker 1: the Fourth of July, or people playing their music in
- 16:20Speaker 1: their cards and their houses. This is all just sort
- 16:23Speaker 1: of people generated, generated community sound. So those are basically
- 16:28Speaker 1: the three categories that I saw, industrial trafficking community. Should
- 16:32Speaker 1: we take a break? I think we should. All right,
- 16:34Speaker 1: We'll be right back. I'm gonna go quiet down that
- 16:37Speaker 1: racket outside. I'll be right back. Okay, do you finish
- 17:04Speaker 1: shaking your fist at those teenagers on your lawn. I'm
- 17:07Speaker 1: lucky because we don't have loud We don't have one
- 17:10Speaker 1: neighbor on one side, and our neighbor beside us is
- 17:13Speaker 1: pretty quiet. But I do live near and I've talked
- 17:15Speaker 1: about it before, a pretty main road, and you you
- 17:19Speaker 1: kind of get used to it. But I also yearn
- 17:21Speaker 1: you know, to be a few blocks in. But you know,
- 17:24Speaker 1: you can't pick up your house and move it. So
- 17:26Speaker 1: what are you gonna do? You get used to it?
- 17:28Speaker 1: You can, but it's really expensive. Well, no, that is true.
- 17:31Speaker 1: You can move a house sometimes. Didn't we do an
- 17:33Speaker 1: episode on that once? How to Move a House? Yeah?
- 17:36Speaker 1: I think I don't know if we did one just
- 17:38Speaker 1: on that. It may been like historic districts or something.
- 17:41Speaker 1: I don't know. And by the way, that episode we
- 17:43Speaker 1: couldn't think of the other day was crumple zones. Oh boys,
- 17:47Speaker 1: So we did do a whole episode on crumple zones.
- 17:49Speaker 1: We did. Boy, we were scraping the bottom of the
- 17:52Speaker 1: barrel there. But I remember that being an interesting episode though.
- 17:56Speaker 1: It was totally interesting. Well that's the stuff you should know, way,
- 17:59Speaker 1: isn't it, Chuck? Uh? It is? Indeed, should we talk
- 18:02Speaker 1: about hearing damage? Yeah, So, like I was saying, there's
- 18:06Speaker 1: that the kind of new type of hearing damage that
- 18:08Speaker 1: we're wrapping our minds around. That is like the death
- 18:11Speaker 1: of the neurons that are supposed to transmit the electrical
- 18:14Speaker 1: impulse to the brain, and so we don't hear very well.
- 18:18Speaker 1: Our our communication is garbled, and yet you can pass
- 18:21Speaker 1: a traditional hearing tests no problem. Um. But other research
- 18:27Speaker 1: is really starting to unfold, like less um less predictable
- 18:32Speaker 1: ways that that noise and noise pollution actually affects our health.
- 18:36Speaker 1: And it's like our entire system is negatively affected by
- 18:40Speaker 1: noise and noise exposure. It is, and it it basically
- 18:44Speaker 1: at the beginning of the whole process is triggering the
- 18:48Speaker 1: same exact thing that triggers your fight or flight response. Uh,
- 18:52Speaker 1: Like you're gonna have the same reaction to you know,
- 18:55Speaker 1: if you hear uh a siren go by, the same
- 18:58Speaker 1: thing is happening in your as far as your brain knows.
- 19:01Speaker 1: Then what happens if like a bear walks up to
- 19:05Speaker 1: you and roarers. Yeah, So, like our our hearing is
- 19:09Speaker 1: always on and it's always on the lookout for, um,
- 19:13Speaker 1: a potential threat. And one of the ways that a
- 19:16Speaker 1: potential threat can give itself away is by making a sound. Right.
- 19:19Speaker 1: It was, like I was saying earlier, Like we've been
- 19:21Speaker 1: around waterfalls and the sound of waves in our evolutionary
- 19:24Speaker 1: history for so long that basically it seems like when
- 19:27Speaker 1: you're born, you come equipped with this. Don't worry about
- 19:31Speaker 1: that sound. Actually you can be soothed by it. It's
- 19:33Speaker 1: not something that should stimulate your fight or flight response.
- 19:37Speaker 1: But we've lived around industrial machinery and the sound of
- 19:41Speaker 1: a text message or a leaf blower, the stupid leaf
- 19:45Speaker 1: blowers for such a little amount of our evolutionary history
- 19:49Speaker 1: that our minds are not at all attuned to those
- 19:52Speaker 1: things or um, we haven't kind of adopted this idea
- 19:56Speaker 1: that a leafblower is non threatening and so it stimulates
- 19:59Speaker 1: the fight flight response and is when we hear it.
- 20:02Speaker 1: That's right, So you're gonna hear that sound, you're amygdala,
- 20:06Speaker 1: which we've talked about plenty uh contributes to emotional processing,
- 20:11Speaker 1: is going to send that same distress signal to the hypothalamus. Again,
- 20:15Speaker 1: that gets if you are in a fight or flight response,
- 20:18Speaker 1: which is why you probably want to run screaming if
- 20:20Speaker 1: you here too many sirens, you're here too many leaf blowers,
- 20:24Speaker 1: and then that's gonna signal your adrenal glands to get
- 20:28Speaker 1: your adrenaline going. And I believe cortisol gets going as well.
- 20:33Speaker 1: It's like literally mimicking fight or flight. Yeah, And so
- 20:36Speaker 1: they figured out that like people who are continuously chronically
- 20:40Speaker 1: exposed to sound, like say people who live like really
- 20:42Speaker 1: close to an airport, really close to the subway tracks,
- 20:46Speaker 1: or um, people who work in a really noisy factory,
- 20:51Speaker 1: they have all sorts of crazy random health problems, like
- 20:55Speaker 1: their kids sometimes have low birth weight. Obviously, they can
- 20:59Speaker 1: develop tonitus um heart disease, obesity, diabetes, UH. There, their
- 21:05Speaker 1: children who are exposed to to chronic noise can have
- 21:08Speaker 1: UM cognitive impairments, um, high blood pressure, like all sorts
- 21:12Speaker 1: of crazy stuff. And so you think, well, okay, that's
- 21:16Speaker 1: that's like, that's terrible anybody who has to live near
- 21:19Speaker 1: noise or work near noise, like we should do something
- 21:21Speaker 1: about that. But it's even worse than that, Like, noise
- 21:24Speaker 1: pollution is even more insidious than that, because you don't
- 21:27Speaker 1: have to be chronically exposed to it. You don't have
- 21:30Speaker 1: to live in a place where you're like, this is
- 21:32Speaker 1: an objectively noisy place that I live or work in
- 21:35Speaker 1: to still suffer from the effects of noise pollution. Yeah,
- 21:40Speaker 1: I mean it can affect you when you're sleep because,
- 21:43Speaker 1: like you said, your ears are always on. It's not
- 21:44Speaker 1: like you go to sleep and the ears say, well,
- 21:46Speaker 1: I'm gonna take a nice break. That would be a
- 21:49Speaker 1: fantastic evolutionary addaptation. Actually, well, actually it would these days.
- 21:55Speaker 1: It wouldn't be the mountains, the mountain lions, saber tooth
- 21:58Speaker 1: tiger days. Yeah. Nice. If there was a switch and
- 22:01Speaker 1: you could kind of control that, it would be so nice.
- 22:03Speaker 1: I think the switches, the white noise wave machine is
- 22:06Speaker 1: that switch, Yeah, which I've gotten addicted to such that
- 22:11Speaker 1: I have to travel with him now. Yeah, everywhere I
- 22:14Speaker 1: go I've heard that. Yeah. Basically, once you start, you
- 22:16Speaker 1: can't go back. Yeah, I like it, though, I do.
- 22:18Speaker 1: Brown noise is my drug of choice. It sounds so
- 22:21Speaker 1: gross though brown. Yeah. I make a brown noise every morning,
- 22:27Speaker 1: you know what I mean? Wow, I was not expecting
- 22:31Speaker 1: danger Field to make an appearance. Well that's what you meant, right,
- 22:34Speaker 1: poop or no? Yeah, I mean I guess anytime I
- 22:37Speaker 1: hear brown, I think it's poop. You know, you think
- 22:41Speaker 1: of that or you think of ween the band, did
- 22:43Speaker 1: they have a brown song or album? They talk about
- 22:46Speaker 1: the brown thing, the brown sound, and brown is just
- 22:50Speaker 1: sort of their color and how they used to talk
- 22:51Speaker 1: about sound. And I've heard other groups talk about brown sounds.
- 22:54Speaker 1: So what does brown sound sound like? Well, brown noise,
- 22:57Speaker 1: you know if white noises, brown noises o middle. Yeah,
- 23:06Speaker 1: it's sort of a lower lower end. And if you
- 23:08Speaker 1: actually play it through a speaker, like if you put
- 23:10Speaker 1: it on your phone and play it through a little bluetooth,
- 23:12Speaker 1: you can get some good base and it just it
- 23:14Speaker 1: really works. Wonders for me. I should try brown noise
- 23:17Speaker 1: or even white noise. I've been using um chrome noise
- 23:21Speaker 1: where it's like, kid, do do do do do, And
- 23:24Speaker 1: it's really not helping me sleep at all. You're like,
- 23:28Speaker 1: you're like, I have the sound of a early Internet
- 23:31Speaker 1: connection being made a constant um. Did they ever name that?
- 23:38Speaker 1: They should have named that great? Yeah, I don't know.
- 23:41Speaker 1: I just call it whatever it was. They called it
- 23:43Speaker 1: the ticket wichet um. Interrupted sleep, though, that's that's the
- 23:50Speaker 1: big problem, or one of the big problems, because your
- 23:52Speaker 1: ears are always on. If you have uninterrupted sleep or
- 23:56Speaker 1: poor sleep overall, you're gonna be tired. Obviously, your creativity,
- 24:00Speaker 1: memory can get impaired. Your creativity is going to be low.
- 24:03Speaker 1: You're gonna have impaired judgment, your psychomotor skills might be impacted.
- 24:08Speaker 1: You might have more headaches. They've done studies. If you
- 24:11Speaker 1: live near airports and stuff like that, or uh, you know,
- 24:14Speaker 1: next to like a rail yard, you're gonna have more headaches.
- 24:16Speaker 1: You might take more sleeping pills as a result. Um,
- 24:20Speaker 1: you might be more prone to minor accidents, and you
- 24:23Speaker 1: are going to be more prone to seek uh psychiatric
- 24:26Speaker 1: treatment in your life. They like studies have shown this. Yeah,
- 24:29Speaker 1: there's a study of people living near European airports. They
- 24:34Speaker 1: found a tendestible increase in aircraft noise was associated with
- 24:38Speaker 1: a twenty eight percent increase in anxiety medication, and that
- 24:42Speaker 1: people um were also likelier to have more likely to
- 24:46Speaker 1: have symptoms of depression. So again all this is just
- 24:50Speaker 1: from like having not good sleep, which is bad enough,
- 24:54Speaker 1: but apparently Chuck it even gets worse because even if
- 24:57Speaker 1: your sleep isn't disturbed where you're waking up and not
- 25:00Speaker 1: getting sleep because of noise, like you get used to it,
- 25:05Speaker 1: the noise is still affecting you while you're sleeping because again,
- 25:09Speaker 1: your ear never turns off. It's always on the listen
- 25:12Speaker 1: out for some sort of threat creeping up on you.
- 25:15Speaker 1: And so if you're exposed to noise while you're sleeping,
- 25:18Speaker 1: it's still has that stress effect on you. And what
- 25:22Speaker 1: they've figured out is that one of the problems of
- 25:25Speaker 1: just being chronically stressed through something like noise and I
- 25:28Speaker 1: think stress in general, is that UM it affects I
- 25:32Speaker 1: think it's called the end athelium, which is the lining
- 25:35Speaker 1: of your blood vessels, and they respond to chemicals that
- 25:39Speaker 1: tell them to constrict to relax UM, and they get
- 25:43Speaker 1: constricted when they get stressed, when they're exposed to stress
- 25:47Speaker 1: like cortisol or something like that comes along and says constrict.
- 25:50Speaker 1: And when they do that, you get high blood pressure.
- 25:53Speaker 1: You can end up with heart disease, you can end
- 25:55Speaker 1: up suffering from heart attacks. And what's insane is they
- 25:58Speaker 1: figured out that after one night of being exposed while
- 26:03Speaker 1: you're sleeping to something like train sounds um your endothelium
- 26:10Speaker 1: it starts suffering, like it doesn't function as well after
- 26:14Speaker 1: just one night of that. Right, Like, isn't the idea
- 26:18Speaker 1: that you can have no other sort of poor health
- 26:21Speaker 1: markers and it can actually be brought on because of
- 26:24Speaker 1: this noise. Right, Yes, while you're sleeping, you're still getting sleep,
- 26:27Speaker 1: but it's still happening to you while you're sleeping. And
- 26:29Speaker 1: not only like high blood pressure um or um like
- 26:34Speaker 1: a heart attack or something like that coming down the road,
- 26:36Speaker 1: but also like diabetes, obesity. There's a lot of things
- 26:40Speaker 1: that we're figuring out are are tied to the lining
- 26:44Speaker 1: of the blood vessels and whether they're healthy or not.
- 26:47Speaker 1: It's a huge predictor of a whole range of diseases.
- 26:50Speaker 1: And when you hear noise, that's your stressors trigger your
- 26:56Speaker 1: endothelium to constrict, and that is a really bad thing.
- 27:00Speaker 1: It is um here in the United States. We kind
- 27:03Speaker 1: of started studying the stuff in earnest in the seventies.
- 27:08Speaker 1: That was when uh pollution was a big deal just
- 27:11Speaker 1: all around in the United States, and we started to
- 27:14Speaker 1: say things like, hey, maybe you shouldn't just um have
- 27:16Speaker 1: a family picnic and then just uh pick up your
- 27:20Speaker 1: blanket and dump all the trash on the ground like
- 27:22Speaker 1: they did on that episode of Madmen and on Anchorman
- 27:25Speaker 1: where they're all eating McDonald's And I saw a guy
- 27:30Speaker 1: throw a fully like McDonald's thing out the window day
- 27:35Speaker 1: the day and smashed on the sidewalk. Oh my god,
- 27:37Speaker 1: And I was just like, who who does that? Still, Yeah,
- 27:40Speaker 1: that's the problem is is we're at a place in
- 27:44Speaker 1: in our country's history where if you confront people like that,
- 27:47Speaker 1: there's a chance you're gonna get shot for confronting someone
- 27:50Speaker 1: like that. But I don't confront But that's like, that
- 27:53Speaker 1: isn't the kind of behavior you should under normal circumstances,
- 27:56Speaker 1: non shooting circumstances, feel perfectly fine confronting somebody about like
- 28:00Speaker 1: what what is wrong with you? Like we're so far
- 28:02Speaker 1: beyond that, Like everyone knows you shouldn't do that. It's
- 28:06Speaker 1: just insane. I got into a good fight with him
- 28:10Speaker 1: in my brain. Yes, I know, Like what, like, where's
- 28:13Speaker 1: the solution, where's the answer? I don't know, man. I
- 28:17Speaker 1: think the zen path is you go pick up that
- 28:18Speaker 1: McDonald's cup and throw it away and and say a
- 28:22Speaker 1: prayer for that person good luck. Uh So. Yeah. New
- 28:26Speaker 1: York uh is where they started studying this stuff in
- 28:30Speaker 1: the seventies because it was kind of wrapped up, like
- 28:32Speaker 1: I said, folded into larger pollution studies. They're like, well,
- 28:35Speaker 1: we might as well talk about noise pollution. New York
- 28:38Speaker 1: is a place to do it, and they did. There
- 28:40Speaker 1: were a couple of studies in the nineteen seventies about
- 28:42Speaker 1: subway noise that really sort of gave put the whole
- 28:47Speaker 1: thing on some terra firma as far as the health
- 28:50Speaker 1: effects and and and learning effects. In the case of
- 28:53Speaker 1: kids at PS ninety eight in Manhattan, it was very
- 28:56Speaker 1: close to the train tracks there, the subway train track close. Yeah,
- 29:01Speaker 1: like two twenty feet away. And they found and this
- 29:05Speaker 1: is this is pretty startling. They found that the kids
- 29:07Speaker 1: that were closest to the train tracks were eleven months
- 29:12Speaker 1: behind their classmates. That were on the other side of
- 29:14Speaker 1: the school. Yeah, on like not in another school, just
- 29:17Speaker 1: on the other side of the school. Yeah, almost a
- 29:20Speaker 1: full well, I mean that is basically a full school year,
- 29:25Speaker 1: because you know with summer's often stuff, that's an academic
- 29:28Speaker 1: year plus that they were behind. And they installed acoustic
- 29:32Speaker 1: tiles in the classroom and some dampening devices, and they
- 29:37Speaker 1: did a follow up study and the gap had closed basically,
- 29:41Speaker 1: So I mean there's proof right there, like your kids
- 29:43Speaker 1: are not learning as well if they're near that subway noise.
- 29:46Speaker 1: There's another kind of landmark study in the seventies in
- 29:49Speaker 1: New York that established the concept of noise pollution at
- 29:53Speaker 1: a place called the Bridges Apartment high rise or a
- 29:56Speaker 1: cluster of them in Manhattan that I believe I've maybe
- 30:00Speaker 1: drives under or really really close, um. And the traffic
- 30:08Speaker 1: noise is so bad that even as high up as
- 30:10Speaker 1: the eighth floor, the traffic sound is about the level
- 30:14Speaker 1: of a vacuum cleaner. And like just sitting in your
- 30:17Speaker 1: apartment you have to raise your voice to be heard, um,
- 30:21Speaker 1: which I mean, just the stress of that I can't imagine,
- 30:26Speaker 1: Like that's an inhabitable, uninhabitable place. I believe people are
- 30:30Speaker 1: still living there as well. UM. But the the this
- 30:34Speaker 1: this study found that children living there were far behind
- 30:38Speaker 1: it reading comprehension at listening comprehension uh, and just weren't
- 30:42Speaker 1: learning as as quickly as other kids their age who
- 30:46Speaker 1: did not live in the bridges. So those two studies
- 30:49Speaker 1: together from New York kind of established this idea like, Okay,
- 30:53Speaker 1: there's a there's a real problem with noise pollution UM.
- 30:57Speaker 1: And then it just went away for many, many years,
- 31:00Speaker 1: is until about two thousand eleven when the WHO. There's
- 31:04Speaker 1: a bunch of other studies, a lot of the other
- 31:06Speaker 1: ones that we've restaurant so far came out around two
- 31:08Speaker 1: thousand ten, two thousand eleven two. I'm not sure what
- 31:11Speaker 1: exactly kicked it off, but there was a big spade
- 31:13Speaker 1: of them. But then the WHO released a really big report,
- 31:16Speaker 1: not the WHO, the band, the World Health Organization. They're
- 31:19Speaker 1: another loud band actually, and UM, yeah, they felt terribly
- 31:23Speaker 1: guilty about causing hearing loss in their their fans, so
- 31:26Speaker 1: they launched the study of UM uh basically all of
- 31:31Speaker 1: Western Europe. UM. They looked at UM I think something
- 31:36Speaker 1: like five hundred different studies and did a meta analysis
- 31:39Speaker 1: of them to calculate what's called the disability adjusted life
- 31:43Speaker 1: years or dailies that were lost in Europe every year
- 31:46Speaker 1: two noise pollution. Yeah, And the idea of a daily
- 31:51Speaker 1: is they can't. They basically say, it's like the healthy
- 31:54Speaker 1: years of your life that are end up being lost
- 31:59Speaker 1: to this human made noise that you're living with. And
- 32:04Speaker 1: it's kind of a sort of an esoteric way to
- 32:06Speaker 1: think about it, but once you wrap your head around
- 32:09Speaker 1: it, it it makes a little bit more sense. But they
- 32:11Speaker 1: found that at least one million healthy years of life
- 32:15Speaker 1: are lost every single year only just in Europe due
- 32:20Speaker 1: to noise pollution. A million healthy years of people's lives annually. Yeah,
- 32:25Speaker 1: And that that means because of all of the disease
- 32:28Speaker 1: burden that noise pollution produces in humans, that that's how
- 32:32Speaker 1: much of our our healthy lifespan is shaved off every
- 32:36Speaker 1: year collectively, or how much Europe's is. And they did
- 32:39Speaker 1: a follow up study in two thousand and eighteen, Chuck,
- 32:42Speaker 1: and found that actually, no, we got it wrong. It's
- 32:45Speaker 1: one point eight million dailies are lost in Western Europe
- 32:49Speaker 1: alone each year. So they definitely established through these this
- 32:53Speaker 1: these couple of who studies like, no, noise pollution is
- 32:57Speaker 1: still a thing and we should probably do something about
- 33:00Speaker 1: on it. And there was another study that was released
- 33:02Speaker 1: this past year that said, yes, dailies are significant, but
- 33:07Speaker 1: we may have found a link that shows that noise
- 33:09Speaker 1: pollution can actually straight up kill you under some circumstances potentially. Yeah,
- 33:16Speaker 1: And this one was this is pretty startling because they
- 33:19Speaker 1: looked at herd Uh, well, not necessarily heart attack, but
- 33:22Speaker 1: nighttime deaths. No, I guess it was heart attacks. But
- 33:25Speaker 1: if you die overnight, die in your sleep quote unquote
- 33:29Speaker 1: from heart attacks. Uh, and the link to commercial aircraft
- 33:34Speaker 1: flying over your house, and I guess they had a
- 33:37Speaker 1: way to sort of cancel out all the other factors.
- 33:40Speaker 1: And they got down to the nitty gritty that three
- 33:44Speaker 1: of all nighttime deaths from heart attacks can be attributed
- 33:47Speaker 1: to the sound of aircraft flying overhead while you're sleeping.
- 33:51Speaker 1: That's just like that was it. That was the last
- 33:54Speaker 1: stress response that your body could handle, and you had
- 33:57Speaker 1: a heart attack and died from that sound. They said, like, Okay,
- 34:00Speaker 1: we found a definite correlation, but if there is causation here,
- 34:04Speaker 1: then we can chalk up about three percent of those
- 34:07Speaker 1: that's astounding. It is astounding. We're gonna take a break.
- 34:11Speaker 1: That's the human grossness, and we'll talk about the awful
- 34:15Speaker 1: things that we're doing to our animal friends in nature
- 34:18Speaker 1: right after this, all right, Uh, we talked about a
- 34:45Speaker 1: lot of studies that basically all added up to noise
- 34:49Speaker 1: pollution very bad for human beings, like literally bad for
- 34:53Speaker 1: their health. And and I know we've talked about a
- 34:57Speaker 1: few of these before over the years, especially when it
- 34:59Speaker 1: comes to whale. Uh, but all manner of mother nature
- 35:04Speaker 1: are impacted by this noise. They did a study in
- 35:07Speaker 1: the early two thousands about stress hormones um for what
- 35:12Speaker 1: kind of whales were they right whales? The right whales
- 35:14Speaker 1: in the Bay of Fundy, And they saw and this
- 35:17Speaker 1: was remarkable. They saw a really weird, unexplained declined in
- 35:21Speaker 1: the stress hormone concentrations that went away and then came
- 35:25Speaker 1: back up again. And they eventually realized it was a
- 35:29Speaker 1: halt in the shipping in the bay after eleven happened. Yeah,
- 35:34Speaker 1: because shipping is probably humans noisiest marine endeavor that we
- 35:40Speaker 1: do all the time constantly. And the idea of a
- 35:44Speaker 1: break and that having being connected to a huge decline
- 35:48Speaker 1: in stress hormones in whale poop. That's that's significant. But
- 35:51Speaker 1: it was an accidental discovery, and I think it led
- 35:54Speaker 1: other people to start studying stuff like that, like the
- 35:56Speaker 1: effects of noise on wildlife. And there was US I
- 36:00Speaker 1: think University of Idaho. I'm sorry. If it's Idaho State,
- 36:04Speaker 1: please don't be mad. I think it's okay. UM a
- 36:07Speaker 1: study from two thousand twelve where researchers set up like
- 36:11Speaker 1: what they call the Phantom Road, which is basically they
- 36:14Speaker 1: have fixed a line of loudspeakers to some trees out
- 36:17Speaker 1: in the wilderness that stretched about a half a mile
- 36:20Speaker 1: in length, and um, they just played road and traffic
- 36:25Speaker 1: noise and not like city stuff, just like the kind
- 36:27Speaker 1: of stuff that possibly a remote road through the wilderness
- 36:31Speaker 1: would sound like. Because they recorded it in Glacier National
- 36:34Speaker 1: Park on a road there, and just from that, just
- 36:38Speaker 1: from like this rural Glacier National Park road noise, something
- 36:42Speaker 1: like more than a quarter of all the birds in
- 36:44Speaker 1: the area just left. They were like, we're moving, We're
- 36:48Speaker 1: going to Canada. So everybody in the United States, Yeah,
- 36:53Speaker 1: you know, I think I definitely noticed, and I heard
- 36:56Speaker 1: other people talk about UM in like April of last
- 37:01Speaker 1: year when things really slowed down commuter and traffic wise
- 37:05Speaker 1: due to the pandemic. And I don't think it was
- 37:08Speaker 1: just um our our imaginations, but there were there was
- 37:12Speaker 1: a lot more bird activity going on. Uh. And I
- 37:15Speaker 1: remember I think I remember us even talking about it.
- 37:19Speaker 1: Um or maybe it was just quieter for us, so
- 37:22Speaker 1: we noticed the more or maybe a combination of both,
- 37:24Speaker 1: but there was there was a difference. And when you know,
- 37:27Speaker 1: when shipping stops after nine eleven or when um traffic stops,
- 37:32Speaker 1: nature says, oh uh, the the human a holes are gone.
- 37:38Speaker 1: Now we can start behaving normally again. Yeah, like things
- 37:41Speaker 1: are back to normal. Um. And that's I mean, that's
- 37:44Speaker 1: just on land. Also, they found that Idaho study found
- 37:47Speaker 1: that the birds that stuck around lost a bunch of
- 37:49Speaker 1: weight which they would have needed to migrate, so maybe
- 37:52Speaker 1: they couldn't leave even if they wanted to. But those
- 37:55Speaker 1: that was the land study. There's been other studies on land.
- 37:57Speaker 1: But it seems like the the we're doing a lot
- 38:01Speaker 1: of damage to marine ecosystems as well, like probably even
- 38:04Speaker 1: more because sound waves travel and water a lot better
- 38:07Speaker 1: than light, which means that most of the animals that
- 38:10Speaker 1: live in the water have really sensitive hearing. That's what
- 38:13Speaker 1: they've evolved to use to communicate and listen out for, right,
- 38:16Speaker 1: So when we make noise, it's really problematic and marine ecosystems, Yeah,
- 38:22Speaker 1: and we make a lot of noise. I mean that
- 38:23Speaker 1: shipping activity we talked about is super disruptive to anything underwater.
- 38:30Speaker 1: When they search for mineral deposits on the sea floor
- 38:33Speaker 1: or under the sea floor, they use these seismic air
- 38:35Speaker 1: guns that are you can hear those things like a
- 38:38Speaker 1: fish can hear that a thousand, thousands of miles away.
- 38:42Speaker 1: Very disruptive. Um, sonar and no We talked about sonar
- 38:46Speaker 1: in in an episode years ago and how that affected
- 38:50Speaker 1: marine life. I can't remember what it was. Did we
- 38:52Speaker 1: do an entire episode on the time they blew up
- 38:54Speaker 1: the beach to whale? Like what to do with the
- 38:56Speaker 1: beach whale? Maybe? I think, but they basically kind of
- 39:00Speaker 1: say now, like they think the reasons Wales beach themselves
- 39:04Speaker 1: is because of these noises and sonar as a big culprit, right, Um,
- 39:08Speaker 1: like it just drives him out of the water, which
- 39:10Speaker 1: sounds bonkers, But if you ever think about how humans
- 39:13Speaker 1: sometimes jump from tall buildings rather than being burned by
- 39:18Speaker 1: the intensity of a fire. I think it's virtually the
- 39:20Speaker 1: same principle. Sure, so we are we have become aware
- 39:24Speaker 1: of just how much noise pollution affects, not just us,
- 39:29Speaker 1: but the environment as well. Like it's it is a
- 39:31Speaker 1: form of pollution. Um. And it seems like you know,
- 39:34Speaker 1: it started to accumulate in the last few years, but
- 39:36Speaker 1: really we've known for a good fifty years that noise
- 39:40Speaker 1: pollution is really bad for everybody. Uh, and yet we've
- 39:44Speaker 1: done almost nothing about it. But we had the start, Chuck,
- 39:48Speaker 1: We started out like we were going to like almost
- 39:50Speaker 1: immediately when we realized how bad noise pollution was in
- 39:54Speaker 1: the seventies, we started to do something about it um
- 39:58Speaker 1: and the federal government passed like th and actually I
- 40:00Speaker 1: saw a fourth one um huge acts that had to
- 40:04Speaker 1: do with basically controlling noise pollution. Yeah, either controlling noise
- 40:08Speaker 1: pollution for people in general, or through OSHA, making sure
- 40:12Speaker 1: people were working in safe conditions or at least had
- 40:15Speaker 1: you know, the ear cans and things they needed to
- 40:17Speaker 1: work safely. And it was, like you said, it was
- 40:19Speaker 1: headed in the right direction. We knew it was bad
- 40:22Speaker 1: and we were trying to stop it. And then the
- 40:24Speaker 1: Reagan administration came along and said, nuts to that, that's
- 40:28Speaker 1: federal regulation. Let's just leave it to the states, because
- 40:32Speaker 1: you ask any governor of any state and they'll tell
- 40:34Speaker 1: you their citizens know to do the right thing, and
- 40:36Speaker 1: they'll do that right thing. And uh so we'll just
- 40:40Speaker 1: leave it up to the states and let them. Uh
- 40:42Speaker 1: they volunteered to face itself out. The Office of Noise
- 40:45Speaker 1: and Abatement Control, uh on paper still exists, but Congress said,
- 40:50Speaker 1: you know, let's just not fund them anymore and let's
- 40:52Speaker 1: keep these laws on the books, but really not worry
- 40:54Speaker 1: about it too much because the states will take care
- 40:56Speaker 1: of it, right, because states always do the right thing. Yeah,
- 40:58Speaker 1: And the states, of course, did absolutely nothing, and it's
- 41:01Speaker 1: partially because they can't do a lot about it. A
- 41:04Speaker 1: lot of noise is really best understood, studied, and regulated
- 41:09Speaker 1: by the federal government. Like what like Georgia has a
- 41:13Speaker 1: bunch of money reserve to study the effects of noise
- 41:16Speaker 1: on humans. Like, no, that's totally a federal kind of
- 41:19Speaker 1: thing to do, you know. And that's what some of
- 41:21Speaker 1: those seventies acts set up, like that, that Office of
- 41:24Speaker 1: Noise Abatement and Control or noise control in abatement, like
- 41:27Speaker 1: it's purpose was to study that kind of stuff. That's
- 41:30Speaker 1: not what states do. So the states have, well not
- 41:33Speaker 1: the states, but usually more municipalities and counties have. They
- 41:36Speaker 1: have taken steps to kind of mitigate sound pollution. Like
- 41:40Speaker 1: there's your noise pollution. There's usually regulations on how early
- 41:45Speaker 1: or late a landscaping crew can work within the city limits,
- 41:49Speaker 1: or some of them say like you can't boom your
- 41:52Speaker 1: stereo or you're not allowed to have that broken glass
- 41:55Speaker 1: muffler on your Harley. Um, like, there's some stuff like that.
- 41:58Speaker 1: But then like if you live kind of under a
- 42:01Speaker 1: flight path, if your town wanted to say, you know what,
- 42:04Speaker 1: you can't fly over our town and wake everybody up
- 42:07Speaker 1: between you know, twelve at night and seven in the morning,
- 42:11Speaker 1: you can't fly an airplane over it. The airplanes would
- 42:14Speaker 1: just be like like, I didn't hear you. Sorry, I
- 42:17Speaker 1: was listening to the Feds who say you can't make
- 42:19Speaker 1: laws like that. Yeah, And you know, I get the feeling.
- 42:22Speaker 1: With municipalities. It is more like complaints from neighbors kind
- 42:27Speaker 1: of noise or the lawn cruise in construction like you
- 42:30Speaker 1: were saying, and less like stuff with big teeth um recently,
- 42:35Speaker 1: Uh weird reason I won't get into, but I was
- 42:37Speaker 1: looking up noise ordinances and Athens, Georgia, and they're kind
- 42:41Speaker 1: of funny when you look at these noise ordinances. It's
- 42:44Speaker 1: like it literally said, like you know, walking down the
- 42:48Speaker 1: sidewalk um yelling at one another, talking about basically drunk kids,
- 42:52Speaker 1: you know, like the French quarter kind of thing. Uh.
- 42:55Speaker 1: It said, you know, this includes hooting and hollering, and
- 42:58Speaker 1: it was something about being able to hear you from
- 43:01Speaker 1: like three feet away, but or noise from your apartment.
- 43:05Speaker 1: But it's you know, it's like good luck with that.
- 43:07Speaker 1: Like you can call the cops on someone maybe, but
- 43:10Speaker 1: there's no teeth or or or what do you call
- 43:15Speaker 1: it when you or enforcement kind of with a lot
- 43:18Speaker 1: of this stuff, aside from singling out people when it
- 43:21Speaker 1: happens in the moment, and you may get a cop
- 43:23Speaker 1: come by and say turn it down. But even if
- 43:25Speaker 1: there's a will to do something, it depends on if
- 43:28Speaker 1: it's like rail traffic or air traffic, like the federal um,
- 43:32Speaker 1: the federal government ties local local towns and counties hands
- 43:36Speaker 1: like they can't do anything about it, and there's um
- 43:39Speaker 1: as a result, there's a lot of noise pollution that
- 43:41Speaker 1: people can't do anything about. There's a um. There's a
- 43:44Speaker 1: town in Canada. I can't remember the name of it,
- 43:47Speaker 1: but it is um. It's got really like a rail
- 43:50Speaker 1: system that goes through it, and it doesn't have like
- 43:53Speaker 1: alarms or like the arms that come down. So trains
- 43:57Speaker 1: have to hank their horns at least three times as
- 44:00Speaker 1: they crossed through this town. And there's a bunch of
- 44:02Speaker 1: different crossings, and they calculated that train horns blair twelve
- 44:09Speaker 1: hundred times a day in this little tiny town. And like,
- 44:13Speaker 1: obviously everybody's going nuts, but they can't do anything about
- 44:16Speaker 1: it because the federal government of Canada is in charge
- 44:20Speaker 1: of regulating rail travel like every other developed or industrialized country. Yeah,
- 44:25Speaker 1: and even if it's something like Osha and like you,
- 44:27Speaker 1: you work in allowed factory and they're trying to regulate that,
- 44:31Speaker 1: they say that a they don't cover all industries they
- 44:34Speaker 1: should cover, and when when they do, it's very inconsistently applied.
- 44:39Speaker 1: And even when they do apply it inconsistently. Um, they
- 44:43Speaker 1: say that these limits aren't even low enough to protect
- 44:46Speaker 1: all the workers anyway from hearing loss said, OSHA regulations
- 44:50Speaker 1: allow workers to be exposed to ninety five decibels for
- 44:55Speaker 1: four hours a day, five days a week, for your
- 44:57Speaker 1: entire forty year career, and that that that's like you're
- 45:01Speaker 1: going to suffer from hearing loss if that's the case. Yeah,
- 45:04Speaker 1: that's like holding a leafblower right right next to you
- 45:07Speaker 1: for four hours a day, five days a week for
- 45:09Speaker 1: forty years. Like of course you're going to lose you're hearing. Like,
- 45:12Speaker 1: that's that's crazy. Well, and then fact you're in the
- 45:15Speaker 1: other health effects that no one ever talks about that
- 45:17Speaker 1: we mentioned in the whole first half of this thing.
- 45:20Speaker 1: And you have an unhealthy population if you're stuck in
- 45:22Speaker 1: one of those places. So we can sit here and
- 45:25Speaker 1: corvetch all day, which we we would love to do.
- 45:28Speaker 1: But there are solutions to this, but we I want
- 45:30Speaker 1: to point out one more time, all these solutions are
- 45:33Speaker 1: zero thanks to the Reagan administration. Um. Instead, there's some
- 45:38Speaker 1: simple stuff you can do to help us humans, Like
- 45:40Speaker 1: you can change aircraft routes, you can build barriers along
- 45:44Speaker 1: roadways and railways. UM. You can even green it up,
- 45:47Speaker 1: like they found that if you use shrubbery and trees
- 45:50Speaker 1: mixed together so that they basically produce a fence, and
- 45:53Speaker 1: you plant them close to the road or close to
- 45:56Speaker 1: the railway rather than close to the place that you're
- 45:58Speaker 1: trying to protect. They do pretty good at reducing the
- 46:02Speaker 1: decibels of the sound the noise pollution coming from the traffic. Um,
- 46:07Speaker 1: that's some easy stuff you can do. And then on
- 46:09Speaker 1: the user end, on the individuals, and there's all sorts
- 46:12Speaker 1: of like acoustic insulation and paneling you can add to
- 46:16Speaker 1: your house to make it a little more soundproof and quieter. Um,
- 46:20Speaker 1: what about those mufflers chuck car mufflers. Yeah, so apparently
- 46:25Speaker 1: the ones that make the sound or not not they're
- 46:28Speaker 1: not good. Yeah, I mean that they could they could
- 46:33Speaker 1: change that. The e p A could get involved and say,
- 46:35Speaker 1: you know what, you can't have those kind of mufflers anymore.
- 46:38Speaker 1: Thank god if they did. As far as the shipping go,
- 46:42Speaker 1: and know, it's always like a Honda Civic or something
- 46:44Speaker 1: that it's like tricked out, like it's some kind of
- 46:46Speaker 1: race car um. As far as the water goes in
- 46:49Speaker 1: the shipping stuff like that. Those big ships, Uh, they
- 46:52Speaker 1: found that if they separate the ship's engine from the hull. Uh,
- 46:57Speaker 1: they are quieter, much quieter, and they even found that
- 47:00Speaker 1: there is uh. I think there's a se reduction in
- 47:03Speaker 1: acoustic energy um six to eight decibels, which is significant. Uh.
- 47:08Speaker 1: And they also found that it is less fuel efficient.
- 47:12Speaker 1: And if they like retrofitted or kind of change the
- 47:14Speaker 1: way they built these ships, I don't know if you can, well,
- 47:16Speaker 1: I guess you can retrofit something. Well, yeah, the propellers
- 47:18Speaker 1: are what's making them less fuel efficient, so you can
- 47:20Speaker 1: easy not easily, but you can take off the old
- 47:22Speaker 1: propellers and put on new ones. Right, But it costs
- 47:25Speaker 1: a lot of money up front, like they will save
- 47:27Speaker 1: in the long run. And I think uh is it
- 47:30Speaker 1: pronounced Marsk, the big shipping company. They spent a hundred
- 47:34Speaker 1: million bucks to do just eleven of its ships, So
- 47:38Speaker 1: that gives you the idea of how much it costs. Uh.
- 47:41Speaker 1: There may be seen some efficiencies if they did more
- 47:44Speaker 1: or something, but it's not cheap. And they have seven
- 47:47Speaker 1: forty ships they've done eleven, so well, I did see
- 47:50Speaker 1: that is actually a very small fraction of all of
- 47:53Speaker 1: the ships involved in shipping that are responsible for the
- 47:56Speaker 1: vast majority of the noise. So if you did just
- 47:59Speaker 1: focus on the worst offenders that would have a significant impact. Yeah,
- 48:04Speaker 1: there's also a huge amount of noise, apparently underwater noise
- 48:07Speaker 1: that comes from offshore wind farms because of the pile
- 48:11Speaker 1: driver that is moved by up and down by the
- 48:15Speaker 1: blades to help produce the electricity to move the turbine right,
- 48:20Speaker 1: And they found that if you just put a perforated
- 48:22Speaker 1: pipe around the pile driver, the pile driver is going
- 48:25Speaker 1: to produce bubbles and those bubbles will dissipate the noise.
- 48:29Speaker 1: Almost all the noise I think like of the noise
- 48:32Speaker 1: coming from those offshore wind farms. That's a really simple,
- 48:35Speaker 1: easy solution. Just do it people. Yeah, and there's one
- 48:38Speaker 1: other thing that I hadn't thought about, but I saw
- 48:40Speaker 1: a couple of places and it really makes sense, is
- 48:42Speaker 1: that the noise pollution we're contributing to marine ecosystems in
- 48:46Speaker 1: particular is just such low hanging fruit that there's no
- 48:52Speaker 1: reason we shouldn't do this. There's some really easy stuff
- 48:55Speaker 1: we can do, like even rerouting shipping lanes is one
- 48:57Speaker 1: thing we can do, and that by doing that it
- 49:00Speaker 1: will actually stabilize marine ecosystems in marine life so that
- 49:05Speaker 1: it will buy us a little time while we're figuring
- 49:07Speaker 1: out much trickier stuff like ocean acidification and things that
- 49:11Speaker 1: are also threats to it. So it's like, just removing
- 49:13Speaker 1: noise pollution would really go a long way toward extending
- 49:17Speaker 1: the UM. I guess the health and vitality of the
- 49:21Speaker 1: oceans while there, you know, while we're combating climate change.
- 49:26Speaker 1: I love it. Let's get all these things going. Our
- 49:28Speaker 1: health is suffering. Let's start with the mufflers. Yeah, that's
- 49:32Speaker 1: just annoyance. Uh. Well, since Chuck said that's just annoyance,
- 49:37Speaker 1: of course, everybody, that means it's time for listener mail. Uh.
- 49:43Speaker 1: This one's pretty short and sweet. I just love it
- 49:45Speaker 1: when we get an answer about something. I think I
- 49:47Speaker 1: might have known this at some point, but we talked
- 49:50Speaker 1: about shrinking as humans. And this is from uh Steve
- 49:56Speaker 1: and Roscoe, Illinois. He says, I've been a long time listener,
- 49:58Speaker 1: never had a reason to reach out, but you my
- 50:00Speaker 1: Arab expertise. I'm a physical therapist, and while listening to
- 50:03Speaker 1: episode about crash testing, you ask why do we shrink
- 50:06Speaker 1: when we get older? What happens is we age, guys,
- 50:09Speaker 1: is the intervertebral discs in our back lose hydration and
- 50:13Speaker 1: as a result, we shrink. Uh. There are six discs
- 50:16Speaker 1: in the cervical spine, twelve discs in the thoracic spine,
- 50:20Speaker 1: and five discs in the lumbar. If each disc were
- 50:24Speaker 1: to lose a minimum of one six of an inch
- 50:26Speaker 1: in height, that adds up pretty quickly, and you can
- 50:29Speaker 1: easily lose an inch plus in your lifetime. The other
- 50:32Speaker 1: thing to consider as we age is our muscles and
- 50:34Speaker 1: tissues get tighter, pulls us into positions of poor posture.
- 50:39Speaker 1: That's right, and this restricts our ability to stand up straight.
- 50:43Speaker 1: You can bind all these things together and all of
- 50:45Speaker 1: a sudden, Josh isn't going to hit his goal height
- 50:47Speaker 1: of six ft. I have to stay on my tippy toes.
- 50:50Speaker 1: New thanks for all the good work. I hope it
- 50:52Speaker 1: didn't step on the toes of a future short stuff.
- 50:54Speaker 1: I think we just did it. Steve. That's Steve Marima
- 50:58Speaker 1: or Marima from Rusco in a way. Thanks a lot, Steve,
- 51:02Speaker 1: that was a good email. We appreciate that big time.
- 51:04Speaker 1: And if you haven't stumbled upon it yet, you should
- 51:07Speaker 1: check out our episode Encarcopania. It is old, but it
- 51:11Speaker 1: was interesting. Yeah, if you have any ethysical therapy needs
- 51:14Speaker 1: in Illinois. Give Steve a cal sounds good guy, Yeah,
- 51:17Speaker 1: head to beautiful Roscoe, Illinois. Come on, if you want
- 51:22Speaker 1: to be like Steve from Roscoe and uh give us
- 51:26Speaker 1: some more info that we were asking for. We love
