Menifee's quantitative decibel limits flow from the General Plan Noise Element via MMC §9.210.060 (Noise Control Regulations). Typical exterior thresholds: 65 dBA / 65 CNEL daytime for residential, 60 dBA nighttime (10 p.m.–7 a.m.), 70 dBA commercial, 75 dBA industrial. Interior residential standard is 45 dBA CNEL. The 'reasonable person' / disturbing-the-peace standard in MMC Title 11 (Peace, Morals and Safety) provides a qualitative backstop for noise that doesn't trigger measured thresholds, e.g., loud parties at night.

Corona FAQ
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.
Menifee FAQ
Does Code Enforcement need a sound meter to issue a citation?
No — MMC §11.07.020 (Unruly or Loud Conduct) and Cal. Penal Code §415 allow enforcement based on a reasonable-person 'plainly audible' standard. Sound meters are typically used for stationary-source compliance under §9.210.060.
What time does the residential nighttime limit start?
10 p.m.–7 a.m. under the General Plan Noise Element / §9.210.060 framework — exterior limit drops by approximately 5 dBA (e.g., 65 to 60 dBA) during these hours.
