Back up beepers are considerably louder than they need to be.
Weirdly, the police sirens in Germany towns like Frankfurt are incessant - it's a very piercing sound, they use them often, all day long, and the sound bounces through the walls of the town which is 5 stories everywhere and narrow streets. In a North American city you rarely actually hear sirens - maybe for firetrucks.
The low hum of gasonline engines really adds up, the electrics are so much nicer that way but I fear accidents.

- bobthepanda 6y agoAbove a certain speed the main sounds you're hearing are tires against the road surface. At low speeds engine noise and braking are predominant, and the former for electric is actually a problem because people are used to hearing the sound of ICE cars when judging to cross the street. The worst bit is that sound walls, at least the ones deployed in America, do not even really fix the problem, because they can reflect sound (so they may reduce immediate area noise but increase it farther away). You would probably want something pretty much like a tunnel.
