Los Angeles FAQ
Can my neighbor be cited if I hear them through the wall?
Yes. LAMC uses a plainly-audible standard at the property line during night hours, and LAPD can issue citations without a formal sound meter reading when violations are clear.
How do I report a noise violation?
Call LA 311 for non-emergency noise complaints or LAPD non-emergency dispatch for active disturbances. Persistent issues can be referred to the Bureau of Street Services.

45 dBA A-weighted interior measurement is the statutory nighttime limit for noise from outside the unit.
Does NYC use actual decibel meters or just plainly audible rules?
Both. DEP uses Type 1 meters for commercial and construction. NYPD more often uses plainly audible standards for street and residential complaints.
