Lol. Car horns and engines add a fair bit, but from my experience, sanitation trucks, delivery trucks, light Rail and busses make the most nuisance noise, follo

Lol. Car horns and engines add a fair bit, but from my experience, sanitation trucks, delivery trucks, light Rail and busses make the most nuisance noise, followed closely by morons blaring bass as they drive. It'll be pretty hard to have a city without most of that, and anyone who likes blaring bass from their car will just go old school and carry it with them. Oh, and neighbors throwing their monthly party, complete with bouncy castle and loud music, loud arguments, and dogs barking, and construction crews, and all sorts. Sharing walls is torture if you are sensitive to noise pollution. IME traffic was pretty far down the list of city noise pollution that actually bothered me.
