This is because they actually have a proper metro system. Unlike in America where public transit is an afterthought. Paris metro trains carry 100s of people per train. Think about that same number of people in cars. That’s why American cities are loud and European cities tend to be a lot quieter.
@@ethancohen4337 yes, the metro system was awesome, but so is New York’s. You’re right though, we just don’t have an adequate public transit in pretty much all of our cities. The main offenders are usually the needlessly noisy box trucks and privately owned gas-to-noise converters that a certain population likes
@@LIRRFAN426 even if they have long delays and the infrastructure quality is degrading, i still find it to be the best, just that there's more to be done to realize its once formerly full potential.
From an engineering perspective, that was pretty interesting, especially how changing grade can reduce noise the most. That said, Ive sat in a park around 23rd st, and noticed that its only the cars that are very loud. Otherwise when all the lights are red, its not THAT loud.
@@littlegamer00 Above 50 kph the noise of the wheels becomes louder than the noise of the motor. That means to reduce noise pollution of cars just going electric is not enough, you also need to reduce speed to 30 kph for example. That would make cities actually quieter. Reducing car density would of course also help, by improving public transport.
I've always loved the scene in a Woody Allen movie where the character's childhood home was right next to a roller coaster ride at an amusement park and the whole dining table shook every time the roller coaster passed.
Not like there’s a huge segment of the population that constantly vandalizes the public transportation, harasses commuters, and free rides the system 🤐
Yes, and EVs will help. They're not magic, but if you've ever stood next to a ICE bus and then an EV bus you know that the second one is massively quieter
@@SecretlyanothernameTrue, but heavy EVs like Teslas and Ford Lightnings still make a shocking amount of tire noise due to their immense weight from their huge batteries.
I haven't seen the use of tracing paper in decades! Would be better to use glass or clear film (such as with his "intelligibility" example) with non-permanent markers to save on filling endless trash cans. Great content and explanations. 😊
@thePavuk Yes, a single bus is louder than a single car. But if you compare the noise of the bus to the noise all the people in the bus would have made if they drove cars, the bus wins by A LOT. So, saying that busses, trams etc. are louder is somewhat dishonest
Love how this is presented as a scientific exercise with real world examples, without the usual "but...costs" disclaimer. I wonder about the "squishy material" train track dampers, though. How long will they retain their squish without breaking?
They'll last quite a while. Each individual dampener is not holding all that much weight, because the load of the train is spread out over so many of them. And the material is quite resilient. I know it's not a 1 to 1 example, but Japan and California have built many high-rise buildings with types of rubber at their base (look up viscoelastic material if you want to learn more), and buildings made with it in the 1980s are still standing strong and weathering earthquakes... which when you think about it, are just really loud sounds that turn the Earth's crust into a speaker diaphragm. xD
in the U.S., we can afford to cut our military budget** wayyy back to do something like this. our taxes would actually go to something that benefits the people. ** [w/r/t to *amount* we spend on the former, not its existence in the first place]
All of the comments talking about EVs solving the issue of cars being loud - above a speed around 50km/h or 30mph, it's noise from the tires and wind that dominates over engine noise, so EVs will make just as much noise as petrol and diesel vehicles. Good land use planning and proper implementation of noise mitigation measures like low-noise road surfaces and noise barriers will help reduce traffic noise in cities more generally, but this isn't always practical in already built-up areas (good for new areas though). I'm sure Raj would love if we could take all the roads and push them somewhere else, but that just isn't possible. Best to do as much as is practical.
I used to mix in arenas and an important consideration is that you cannot combat a reverberant space with more direct level (turning the sound up doesn’t improve the intelligibility or direct:reflected ratio). There is a 1:1 relationship between direct and reflected sound when it comes to sound reinforcement, you push more into the room and then that much more also comes off the walls and surfaces
Totally! "Since that usually isn't an option..." Of course it is! It's always an option to repurpose streets to sth more valuable and focus on environmental friendly transport systems. It's always politicians deciding actively to do the one or the other.
I'm fascinated by the aerial footage around 1:43. I live in that general area but have never seen the park in that general arrangement. Looks like I have the rest of my evening planned out 😔
CARS are loud. They are detrimental in so many ways. Go walk on your nearest American suburb road vs a neighborhood without anyone driving and hear the difference! Cars are the worst
4:48 This is a perfect way to explain the auditory processing issue I have. My hearing is great, but my ability to filter out background sounds isn't so great.
Cars make the noise (and polution, and waste materials and space). How about we not redesign cities around cars instead and use transit and active modes of transportation.
The biggest issue with urban noise is cars and car horns. Cars produce lots of broadband noise, and car horns are both tonal and impulsive. If we forced motorists out of NYC permanently, it would be a better place to live. You’ll get an idea of the benefits in a couple weeks when congestion pricing comes into effect.

CITIES. ARENT. LOUD. CARS ARE! I love how more and more comment sections on city related videos are beginning to realise that cars a big major problem in all things related to city designs lol
Virtually none of these ideas are actually practical or have anywhere near the impact compared to their cost. Keep working on it though, it's a good goal to hear nature again.
I live a few miles from an airport, and when the wind blows a certain direction, the drone of the airplanes on the ground waiting to take off is extremely loud. Because there are always multiple aircraft waiting in line, the sound is a constant rumble.
I've noticed subways don't screech as much as they used to. But for me the real noise makers were the elevated rails. It was as if all the steel columns and beams that support them were designed to amplify sound.
Fun fact, but modern or even decent elevated rails don't make that much, or even don't make noise at all. It's just the US living with bad and unmaintained transit.
these elevated sections of NYC subway were probably built around a century or more, that concept about noise pollution/dampening didn't seem to be widely known (or if it was, then they are widely ignored), and construction design is centered around materials like steel or iron (but not concrete)... Materials that could easily conduct electricity... and vibration and noise as well...
I wanna see how quiet it is at the top floor penthouse of the luxury condo towers in nyc. Especially when there's cloud cover or snow beneath the building heights
Great article, WSJ! Cheers! Acoustics and their applications are fascinating. I love the focus on design of cities to significantly eliminate unwanted noise. Infrastructure noise can also be leveraged within cities to increase situational awareness and protect assets through innovative new optical technologies. Both are required to enable both smart and quieter cities.
they could simply redirect them. u know actually getting rid of them is much easier said than done (but they are trying, with the upcoming congestion pricing scheme; was once on hold due to huge opposition (June-November 2024), it'll be slated to be put in effect in about a month or so).
The most effective way to design a city up for noise is to make it walkable and bikeable lol, not remove people from the roads, WJS See Cities Aren't Loud, Cars Are by NotJustBikes
I was hoping for some more in depth acoustic analysis, like how the sound would diffract over embankments and walls and actual engineering solutions to help prevent that. It would be nice if it were a little bit more scientific and nuanced than the two dimensional“Green nature: good. Large corporations: bad.”
I should mention just like those train tracks are cushioned from the ground, buildings can be isolated from the ground too so sound doesnt transfer into them. But there's too much to cover in just 8 mins.

He never says cars aren't loud, but they aren't the only issue, and removing them won't fix poor design and lack of dampening for other sources. Also, the loudest vehicles are not passenger vehicles, and they can't really be removed if you want the trendy cafe you visit to have anything to sell you or if you want your city to have any substantial economy that isn't just pushing numbers around till someone figures out you're not doing anything. And idk about your experience but buses are VERY loud too. Much louder than 10 passenger vehicles at the same speed. Rail is an easy fix to dampen. Light rail is ideal and my country has lots in cities.
Why doesn’t the nyc subway use rubber wheels like Europe. Also is there a way to transform the elevated lines into concrete structures like the Van Wyck air train. You almost never hear the air train zooming by
the main point of steel wheels and steel rails is the low friction between them, it massively boosts the energy efficiency, rubber pretty much negates that. It do have a specific niche it can be used with, but the trade off is just too big to implement across the network, even in Europe.

The squealing of the subway at union square and most of the A division tunnels in general is criminal. I noticed grease that was there to try to improve this (maybe?) but it doesn't do nearly enough. It feels like nails on a chalkboard amplified through concert speakers right in front of your head
Rock Wool is pretty good. MLV is good but expensive. I'd stay away from compressed acoustic fiber glass as it's absorption frequency range is not flat. Really depends on your application.
I‘m not so sure about stricter noise protection standards. This would make building housing and new infrastructure more complicated, buerocratic and expensive
i like how they mention brooklyn steel but the sound barriers don't work as well as they think, it is just lucky that the spot across is a nycha and what can poor people do abt that? nothing lol. I've been around there so many times and noise leaks out just as bad
It's all a neat idea, the easiest solution is to move out of NYC and other big cities into suburbia. Take it to the next level and move to a mountainous region with these different levels of terrain already naturally implemented.
It has never been more expensive to visit New York City: on.wsj.com/3ZxCxtV
There should be some noise standard applied to vehicles too. When I worked in Paris last year it was amazing how peaceful the streets were.

Cities aren't loud, cars are. Carcentric city design bankrupts cities and kills habitability.
The sound of the new york subway is deafening so I guess its more than just cars
Fans and heating/cooling systems contribute significantly to the overall noise levels.
City trains, trams, busses... are much much louder then cars. Except you live in city where drivers use horns more then gas pedal.
@thePavuk
Yes, a single bus is louder than a single car. But if you compare the noise of the bus to the noise all the people in the bus would have made if they drove cars, the bus wins by A LOT.
So, saying that busses, trams etc. are louder is somewhat dishonest

Love how this is presented as a scientific exercise with real world examples, without the usual "but...costs" disclaimer.
I wonder about the "squishy material" train track dampers, though. How long will they retain their squish without breaking?
Exactly. Is it cheaper to cover the city in sound dampening foam that’ll last weeks or just stop it at the source.
They'll last quite a while. Each individual dampener is not holding all that much weight, because the load of the train is spread out over so many of them. And the material is quite resilient. I know it's not a 1 to 1 example, but Japan and California have built many high-rise buildings with types of rubber at their base (look up viscoelastic material if you want to learn more), and buildings made with it in the 1980s are still standing strong and weathering earthquakes... which when you think about it, are just really loud sounds that turn the Earth's crust into a speaker diaphragm. xD
Isolating train tracks isn't anything new, Japan does it for different reasons (earthquakes) but it does also isolate sound as well and can last.
