Noise laws by country

Most countries limit residential noise to around 55 dB by day and 40–45 dB at night, with protected quiet hours in the late evening. Exact figures and enforcement differ — pick a country for the detail.

Illustration of residential noise regulation and quiet hours around the world — Nighttime limits cluster around the WHO's 40 dB guideline for undisturbed sleep.

“How loud can I legally be?” has no single answer — it depends on where you live, the time of day and the zone (residential, mixed or industrial). This guide summarises typical national and widely-adopted municipal rules for education. Always confirm with your local ordinance before acting.

🇳🇿 New Zealand	~55 dBA	~40–45 dBA	Council-set; typically night 10 pm–7 am

The common thread

Three principles recur almost everywhere. First, night is protected: limits drop 10–15 dB after roughly 10–11 pm. Second, limits are often expressed relative to background (e.g. “+5 dB”) rather than as fixed numbers, because a rural night is far quieter than a city one. Third, enforcement is local even where the standard is national. When in doubt, a documented log plus a measured level is what moves a complaint forward.

Soundproofing & noise reduction

Sources & accuracy. Reference levels are drawn from published data by NIOSH, OSHA, the CDC, the WHO Environmental Noise Guidelines and the American Speech-Language-Hearing Association (ASHA). Real-world readings vary with distance, room acoustics and the specific source, so treat every figure as a typical value rather than an exact constant. Last reviewed 2026-08-11.
