Sound and Health: Cities

2019-05-17 | 🔗

Is our blaring modern soundscape harming our health? Cities are noisy places and while people are pretty good at tuning it out on a day-to-day basis our sonic environments have serious, long-term impacts on our mental and physical health. This is part one in a two-part series supported by the Robert Wood Johnson Foundation about how sound can be designed to reduce harm and even improve wellbeing.

Thanks to the Robert, Would Johnson Foundation for underwriting this special to part series about the power of sound to effect, an influence, our health and well being the robber Would Johnson Foundation is working alongside others to build a culture of health for everyone in America, learn about them at our W J, F, DOT, org This is ninety nine percent. Invisible I'm roman Mars! nearly every where we go we're bombarded with human made sound. It's a scam bad in cities, cities in the past think about where you'd have horses and buggies airy here club. You'd here banging of word against stone, very noisy experiences, that's Joel Becker he's a composer and founder of a sonic branding and design company called man made music. Then car came along and were sharing the road with these
and sir. Not only did you have the horses One rate of speed the cars at a different way to speed up lots of honking of the horns. It must have been a cocoon this mass, but he's, got even worse when cars came to dominate the roads. He fast forward to really what the sound scapes were. Let's say in the fifties, so in the future, these. It was all about muscle cars. It was all about the loudest car. You could have mustangs corvettes that were really really loud, We might not have muscle cars anymore, but our cities are still noisy places were pretty good. At two need it out, but our sonic environments have serious impact on our mental and physical health. So is the blue,
green modern, sounds, gape slowly, killing us. This is poor, one of a two part series all about how sound can be designed, create more well being and reduce harm. We re we respond to sound quicker than neither, since it really becomes the arbiter of all our senses but many the sounds. We here are created with very little thought for how they interact with each other. They could be a by product like engine sounds of a computer or they, could be made intentionally like alarm herself on paying add to that the sound of overhead planes, Eric units patio stores pumping music sirens and people talking loudly to be heard over the the noise. You have trucks. Buses, other kinds of transit and then mean a mechanical things like construction. And, of course there are cars. The sound of cars is kind of inescapable, which is depressing
if you think about it, that's Kate Wagner. You might know her from her fantastic blog Mc Mansion, Hell, she's, an architect, and design critic, and she cares alot about sound cars. Tend to drown out other things like Birdsong human speech, the rustling of leaves conversation things that may be or more personal or like that hold in higher like aesthetic value job, common says we need a new approach to sound. One were We decide what we hear and are everyday environment is real. About how, but we use music and sound to make people's lives, you richer and simpler. Joel ones found to be something we're thinking about all the time. But while sitting have more noise laws than ever over half of the world's population. Live in urban areas experiencing way too much noise mood. Sound is measured in decibels, the latter. The sound the higher the number acquired
library is around forty decibels, cardinal, as can be anywhere from like sixty five to eighty two, even ninety decibels. If you're really close to the highway, the does will scan well, isn't linear thy means. Eighty decibels isn't twice ass, loud ass. Forty is actually ten thousand times louder. If you ve ever like had to pull over on this the highway is maybe I was flat tiresome. Get your card. The sheer noise that you hears quite startling, just like the sheer mass of sound, That is an eight lane highway the the level of car noise in a busy city is about the same as having your tv on at the top volume all the time, some silly noises are designed to be allowed to play. Sire an ambulance sirens are a hundred and twenty decibels. We might try to escape all this by sticking in a pair of headphones and cranking up the volume, but depending on what your listening to head
owns can be over ninety decibels. Prolonged exposure to any over eighty decibels. Willie The hearing loss so before we go any further. While we're talking about the idea of sound and health. Do yourself, a favor get into little bit quieter area. In turn, episode down a couple of notice. Your ears will thank you when it comes to city, sound volume is not the only thing hardiness, it's not just how long out the sound. Is it the character The sound whether or not you have control over the situation? That Erika walk she's, a researcher at the Boston University School of Public Health in a Robert, Would Johnson Foundation guarantee for Erika the impact of sound is all about context. I lived in parliament, building and above me, where these neighbours than they had two small kids and the kids used run across the floor twenty four hours a day, the sound
more than fifty or sixty decibels. That's the same volume as the background music and coffee shop, but Erika could feel that sound every moment of every day for different people is different things, but for me it was the rumbling. It's that low frequency sound. You can't hear it, but you know it's there and oh no it's coming from, but you can feel it living close together we're going to make silence that will cross over into other people spaces and that's not always bad. In fact, it's one of the reasons either they appreciate the sound levels like they like here in their neighbors had the barbecue because it makes most like they like hearing their neighbours at the barbecue, because it makes you feel like a sense of community. So there is a positive aspect, but when we don't have control bats, health problems start meteors banner, professor at the University of Pennsylvania, so he's how noise affects our sleep, so noises stress is
I we have little or no control over it, and so The body will excrete stress hormones like adrenaline accord. Is that lead to changes in the composition of our blood? and of our blood vessels, which actually been shown to be stiffer. After a single night of noise exposure, people who A exposed for prolonged period of time have an increased risk. Four cardiovascular disease, including high blood pressure and my the cardinal infarction, but also some studies, a higher risk of stroke, Oh coral, infarction by the way, is another term bore a heart attack, although risk increases are relatively mild relative to other exposures like smoking, for example. This still constitutes a major public health problem, because so many people are exposed to different noise sources and the World Health Organization, published a report on the burden. Disease by environmental noise and they base
He showed that in the western European Member states alone, one points million healthy life years are lost every year due to the exposure, to environmental noise theirs. From the University of Michigan that looked at the effect of lowering sound exposures by five decibels that could save through he point nine billion dollars and healthcare costs and it would so save lives, There are so many other ways that noisy environments are bad. For you think, allowed restaurant. There is the sound of the open born, don't be music, You're shouting at your friend and everyone, this astounding that their friends to its pretty stressful When we get stressed studies show we for comfort, food and alcohol
noise. Also herds are academic performance. Screws up our mood hurts our concentration. Basically, we are being killed by noise and some of us are being killed faster than others more after this support for this special too, port serious, exploring the power of sound to influence. Our health comes from Robert, Would Johnson Foundation the Robber woods some foundation, is working to build a culture of health that insurers. Everyone in America has a fair and just opportunity for and well being which include exploring how our current or future environments will impact daily life learn more at hard W J, F Dot, org we know. Noise causes health problems, but they can be especially pronounced if you live in a less affluent neighbourhood, if we live in a place for them, but with lots of environmental noise, as do many people in american Citys, especially people of color and low income families,
then we have to deal with essentially this mechanical sound, that in shaved off sort of the high frequencies. Just through repeated relentlessness those near factories, highways and flight paths are the loudest, and usually there at the least expensive places to live there. Is a noise equity problem? We should have the choice of living in a space. That is not doing damage to us without having to move. We should have the agency to good health, good hearing health, and we should have agency. For the things that could harm us. Essentially, the most a solution is to make laws some cities car about quiet hours. You run, a noisy leap lower or draw me in your garage at night or else you'll get fund, but there's a the problems with noise abatement laws. For one thing there are often used to target vulnerable people
he's a babe in Lhasa Room, always singled out powerless people People whose livelihoods impeded the sort of middle class vision of a quiet or orderly or bustling city, Et Cetera, sort of like what this sort of bourgeois idea of what the ideal sounds gape would be for the city they. First restrictions on city noise came in the early twentieth century in New York, a ritual named Julia Barnett Rice campaign to silence the horns and whistles from tugboats in nearby poorest. All these noise or bothering her in her Riverside mansion, it's not hard to see the thread of connection from some like Julia Barnett rise in some, unlike barbecue back, the white woman who call the police on a black family having a barbecue last year in Oakland, it was the beginning of what we call gentrification, which is pushing out those. We rely on the city for work in order to satisfy the sort of aesthetic tastes of the wealthier people, whose opinions were more of a concern,
and to those in power. This is very much. Both a literal and sonic displacement. What noise laws is that they aren't very effective so the way, we currently regulate and measure, sound and our communities is by using this decibels. That's Erika Walker. The decimal measures. How loud something else- but most sound meters, only listened to a specific range of frequencies. The kind that we share with our ears- that's called a weighted system. This awaited system that tells us that it's only them sound, semi processed the auditory system. There are important, but there are some sounds we dont process with our ears once the pit this low enough. We no longer here it but feel it. Instead, it's completely vibrational. So it's just essentially that feeling so when
in a community that some flight path- and you say it- sixty five- a weighted decibels, you're subtracting out the components that come from the lower frequencies, so you're leaving out a huge part of the story, not only is that a flawed metric day, using this metric to determine whose eligible for sound proofing criteria Eric is working on a project called the community noise lab, and she hopes that by taking a a wider range of frequencies into account. We can get a better grasp of how sounds affecting our neighbourhood and our health. In the meantime, take Wagner, says that there are steps everyone can take to make things sound a little better. You can make six changes to the spaces you're in there are sort of art actual and design choices that we can make to make our space is a little bit quieter. You can always choose to sort of beef up. The insulation and I have a floating for any other sort of expensive solutions that are more structural too
isolating noise, get also hang thicker curtains, which is coal, because velvet is in well, the curtains might be a solution to noise problems at home, but it I seen the noise from cars and industry requires a fundamental change to the way we live. Often the thing they are making the most noise especially sort of industrial noise, are the things that are perhaps not exactly the healthiest for, environment, for example, it takes more noise, to have a natural gas plan or drill, or do what have you for any kind of serve extractive purposes than it does to have a solar farm, which is almost entirely silent. Quietest city I've ever been in that was a major city was Helsinki in Finland. I was astonished because the matter throw or the subway trains and the buses and what not their silent, the train stations, are very quiet, partly because the majority of their trains or electric. But it's also down
the design of their stations from a mixture of material sound, observing materials and also cycle acoustic tricks like pumping in noise, that has this weird perverse effect of making things seem quite or which is a technique used in offices as well. The Finns are able to make spaces quieter and the idea that they should be quieter seems to be more popular. There perhaps a quieter public spaces play a small part in making Finland reportedly the happier country in the world is a country that is so taken into account. The public good from all aspects, things like health care, child care, social services of robust welfare state and things like their outlook on sustainability, so cleaner, either vehicles make a happier and when they, our less noisy as a great opportunity to create a
richer and more useful sonic landscape, electric cars, don't nap really make a sound. So if you ve ever had one creep up on you, it, really really scary experience door, document says this: silence of electric cars can actually be a drawback total silence, is not a good thing. In fact, Joel says that electric cars need to make noise, or else they will be safe. It's not the people in the our it's for the pedestrians to know that the cars coming, but the opportunity is also to create personality for the vehicle for electric vehicles, He actually worked with Nissan to create an identity for their new electric car. Here it is coming right after In this case, what we were looking to do was create a car that had a person which is really an association with clean energy, one we knew. Is it's gonna be frictionless when you hear a car,
our accelerate, if it accelerates very quickly, let's say and there is a sense of really smoothness lack of friction, There is a almost a natural ambience to it. We actually used had to because we don't want pedestrians to hear it and say: oh, what's that and get hit by the car. A car and it actually had to because we don't want pedestrians, to hear it and say: oh, what's that and get hit by the car Joel once a few your city dominated by natural, sounds, but also sounds that we'd consciously chosen subsidy There are already taking a more thoughtful approach in the Tokyo Subway station each station. Has a little tune associated with it, and if you know anything about the japanese subway system, it is packed. So if you're in the middle of a car and you miss an announcement because its noisy year, sunk yoga Mr stop. The Tokyo trains have a short jingle. Uniquely
each and every station. Along the line like this one for eco grow stay. Turn on the yeoman know. Tat line these little tunes that show up at each station, helps you understand where you are, and also Her pleasing there are there not a screaming announcement. We it live in cities full of intentional sounds with sounds gay. We ve chosen, you might find some new sounds really pleasant or, really annoying. But the nice thing is you get to the This special for yourself because you ll be able to hear them all
