🇺🇸 Noise laws in United States
There is no single federal residential noise limit in the US. The EPA’s 1974 guidance recommends a day-night average (Ldn) of 55 dB outdoors and 45 dB indoors to protect public health, but enforcement is local. Most cities set daytime limits of 55–65 dBA at the property line and nighttime limits of 45–55 dBA, with quiet hours commonly 10 pm–7 am. OSHA governs workplace noise (90 dBA over 8 h, with a 5 dB exchange rate); NIOSH recommends the stricter 85 dBA / 3 dB standard.
How United States's limits compare
Most developed countries converge on a similar pattern: roughly 55 dB by day and 40–45 dB at night in residential areas, protecting a night-time window for sleep. The WHO recommends keeping bedroom noise below about 40 dB (Lnight) outside, which is why nighttime limits cluster there. The table shows how United States sits against others.

What to do about a noisy neighbour
The universal first step is to keep a dated log of the noise and, where possible, a rough level from a sound meter. Most authorities will not act on a single complaint but will on a documented pattern. If the noise is inside your home, reducing what reaches you can be faster than waiting on enforcement — our soundproofing guide covers what actually blocks sound.
Soundproofing & noise reduction
Mass and sealing beat foam. Acoustic panels tame echo inside a room; blocking sound between rooms needs mass-loaded vinyl, door seals and heavy curtains.
