Brazil Revises Municipal Noise Laws, Ending Uniform 10 PM Curfew for Bars and Events

Brazilian municipalities are updating their local "Lei do Silêncio" (Noise Law) to replace the long‑standing 22:00 curfew with rules that consider zone, activity type, and measured noise levels. Under the new approach, establishments in designated entertainment districts may continue playing music after 22:00 if they meet authorized decibel limits, while venues in residential neighborhoods can face stricter limits that may apply even before that hour.

The changes do not constitute a federal waiver of noise controls; the national criminal code still penalises excessive disturbance at any time. Instead, each city can set specific licensing requirements, acoustic‑isolation standards and enforcement mechanisms. Violations can still result in fines, closure orders or loss of operating licences.

Proponents argue the flexibility will boost nighttime economies and tourism, while residents express concerns about increased noise, crowding and public‑order impacts.
