It pains me that noise pollution isn't taken as seriously as other forms of environmental damage when it's the one that most directly impacts (urban) people's quality of life.

> (urban) people's quality of life

Not really. There do exist very noisy countrysides, mountainous areas etc. (Still often because of infrastructure or uncaring dwellers.)

This is almost interchangeable with a light pollution map. E.g. http://www.cleardarksky.com/maps/lp/large_light_pollution_ma... Funny how often human effects on the environment correlate with human population density.

It might be more interesting to subtract one data set from the other, showing how much of the noise is human-induced? Perhaps there are some outliers.

One can already tell you some factors deductively (and verifiedly): it's not the density, it's the presence. Mass is phonoabsorbent; there where you have buildings, you have both noise from the inhabitants and shielding from the constructions.

In the open spaces, one single source can pollute for even ten kilometers or five miles of distance, and more. The added effects of natural acoustics can be worsening - barkings bouncing in the echo from valley to valley, starting in front and returning behind etc.

To all those suffering from noise pollution: go to the hardware store and buy foam weatherstripping for your doors and windows in your room experiencing the noise pollution. Door sweeps, white noise machines, and earplugs also help significantly. Cheap, easy, and high ROI. Other than that buy IEMs, for noise reduction I recommend the Etymotic ER2SE or the Sony WF-1000XM4 if you want wireless noise cancelling IEMs

> earplugs

Can be unhealthy. Earmuffs seem to be as effective and, while you can still get damaged (risk of suction), it's difficult.

Issue: earplugs and earmuffs are designed to reduce noise, not to cancel it - to facilitate that you don't get damage from a bang but can still faintly but clearly hear your colleague calling "watch out". And, reduction in background noise amplifies the impactive - not in absolute but in relative amplitude, not in vibrational strength but in presence.

I often have this thought of how different the world sounded when combustion engines (cars, motorcycles, planes, tractors, etc) weren't ubiquitous.

I happily grew up in the 80s in a place (communist Poland, so rather small car ownership) with very little artificial noise, but that is gone now.

How was it hundreds of years ago?

It'll be interesting to see how electrification of transport changes this. Here in Europe we're phasing out ICE at quite a rate and the proposed euro 7 standards are so strict that it will also alter what the car fleet looks like.

We live on a main road (although it's all relative, it's single lane in both directions and limited to 30mph) and i've already started noticing that the majority of what I hear is now tyre noise.

The cars, trucks and motorcycles with booming exhaust pipes are insufferable. I despise hearing them revving by. I feel like I'm crazy for how much it bothers me. But then I read a story about a man shooting a driver who was just revving up and down his street, so I'm not alone. I spent a week in Helsinki, and was blown away by how quiet it was despite being far more dense than my city.

I so relate. I was once able to test drive a Audi R8 Spyder because the agency I work for works for Audi.

The motor sound isn't anything near quiet. Far from it. But I was astounded to find a button that enables a loud motor sound function.

With this button pressed the sound makes a lot of bikes sound like child toys. I really don't understand how one needs to show off in such a fashion and explicitly expressing a loud (pun intended) f** you to the rest of the world.

It's because the police serve the interests of the owning class, and so prioritize things such as corporate property damage and the ability for workers to get to their jobs.

Note that loud exhaust is not an issue in more affluent neighborhoods... I've been told the number of people driving with loud exhaust is a function of how close you are to the nearest meth house. This is after adjusting the data for level of travel a given road or nearby road

Wow. Cool. Do you have any data on that?

I live near a school (equivalent to middle as well as high school). The rest is a purely residential area.

I feel that living near a school in the morning with mommy driving little Kevin to school in big SUV and little Kevin's older brother revving his engine as much as he can with his car comes probably somewhat close.

What do you mean by this? Got any links handy?

It would be especially sweet if it was a motorcycle cop writing those tickets. Though if I were a cop, I wouldn't want to be a motorcycle cop because they have a higher fatality rate. As a motorcyclist, I'm firmly in the camp about quiet, stock pipes. If I was dictator, I would impound and destroy any vehicle that was too loud.

Also any that have too bright headlights. Crush directly into a cube. And then fine the owner if he doesn't move his cube.

Brightness isn’t necessarily the problem if they are pointed at the correct angle. Lights within spec are annoyingly blinding if set too high.
