How Riverside decides what counts as too loud
Riverside sets numeric limits measured at the receiving property line, with a separate audibility test for amplified sound at night.

How to measure it in Riverside
Measure at the receiving property line and compare against 55 dBA daytime or 45 dBA after 10:00 PM. If the problem is amplified sound at night, there is a second and often easier test: sound plainly audible 50 ft from the building is prohibited between 10:00 PM and 7:00 AM regardless of the measured level.
Record levels with the free online decibel meter, and log the date, start time and duration with each reading. A phone microphone is accurate to roughly ±2 dB and is not a calibrated instrument — enough to establish a pattern, not enough for an enforcement hearing.
Turn your readings into something you can file
Police non-emergency / Code Enforcement will ask when the noise happens and how long it lasts. A live decibel reading answers neither. Pro records a timestamped session — a ten-minute check or a full night — charts the whole thing, and exports a PDF with the dates, times, duration and the statistics that describe a pattern rather than a moment.
- Timestamped sessions with the recording timezone
- Leq and L10/L50/L90 background levels
- Print-ready PDF report, one click
- Your last 25 sessions, kept on your device
Measurements stay on your device on the subscription plans. A phone microphone is not a calibrated instrument — a session establishes a pattern, and this page is not legal advice.
