Noise is a complicated thing. If you're in a neighborhood that's got low-speed traffic and the occasional car engine is what's disrupting your peace, more penetration of EVs will be great. But EVs are also heavy, and cars are getting heavier in general. That isn't going to do you any favors on tire noise. I wouldn't expect the noise coming off of a freeway to change much.
- heipei 6y agoHere in Germany they have deployed so-called "whisper/porous asphalt" on the highways leading into some major city centres. Since it's more porous than regular asphalt it absorbs noise (and rain) much better, but the drawback is that it's more expensive to manufacture and is less durable. Just saying that there are probably lots of different noise reduction techniques that all add up their percentages, but these will only be put in place if noise pollution is taken as serious as it needs to be.
