Decibel Limits: Corona vs Murrieta

How are noise levels measured in Corona?

Code Enforcement uses an A-weighted Type 1 or Type 2 sound level meter on slow response, taken at the receiving property line, typically averaged over a 1-hour Leq with separate analysis of peaks and impulse events.

Does Corona use decibel limits or the disturbance test?

Both. The ordinance allows enforcement based on either an objective dBA exceedance or a subjective finding that the noise disturbs a person of normal sensitivity.

How loud is 55 dBA?

Roughly the level of a quiet conversation or a suburban daytime background. Most normal speech at 3 feet is 60-65 dBA, so music that is clearly audible inside a neighbor's home usually exceeds the limit.

Who takes the decibel readings in Murrieta?

Code Enforcement uses Type 2 meters or contracts with an acoustical consultant for documentation in contested cases. Readings are taken at the receiving property line.
