Sound Meter
Measure ambient noise in decibels (dB) with your mic — current, average and peak, right in your browser.
Turn your phone or laptop into a quick sound level meter. Allow mic access and it shows the ambient noise around you in decibels (dB), live — with the current, minimum, average and peak level, so you can check how loud a room, street, office or fan really is.
🔒 Sound is analyzed live on your device to measure loudness only — never recorded, stored, or uploaded.
Free online sound meter (decibel meter) that turns your phone or laptop into a quick noise meter. Allow mic access and the ambient sound level around you shows in decibels (dB), live — with the current, minimum, average and peak reading plus a rolling graph, so you can check how loud a room, street, office or fan really is. A calibration slider tunes it to your device. Everything runs in the browser — no download, no install — and sound is analysed on your device only to measure loudness, never recorded or sent. It's an approximation (±5–10 dB), not a certified sound level meter.
