AC installed between houses that are close to each other are another menace that makes it hard to sleep if your bedroom is on the wrong side of house. It’s not even the noise level, as it is the vibration and low frequency hum that often has an annoying phase that makes it difficult to ignore. White noise helps a bit, but that only works for people who are okay with blasting white noise in their bedrooms. Same goes for swimming pool pumps. Most places don’t have good laws regarding constant noise levels (as opposed to laws that govern things like loud music at night). Noise pollution is a real problem that affects your health. And most of it could be solved by engineering if the required laws were more strict.
