Try the loudness meter
Practice mode. Nothing you do here is saved or submitted. Tap the button to take a 5-second sample using your device microphone. Real submissions require you to be within 1 mile of the venue you're rating.
Capture a loudness reading (optional)
Phone-mic decibel readings are uncalibrated estimates for rough comparison only.
Why phone-mic readings are estimates
Phone microphones aren't calibrated SPL meters and their response varies by model, case, wind, and even how you're holding them. Treat readings as relative — a venue showing 90 dB is louder than one showing 75 dB, but neither number is a precise measurement.
How the sample is computed
We record 5 seconds of audio and compute the equivalent continuous level (Leq)— the time-averaged sound energy over the window. This is what professional SPL meters report. Brief spikes (a door slam, a laugh) bump the result a little but don't dominate it, which matches the experience of trying to hold a conversation.
