A live decibel meter. Nothing you say or record ever leaves your browser.
Loudscope needs microphone access to measure sound levels in real time. Audio is processed on your device only and is never recorded, saved, or sent anywhere.
Microphone access was not granted, so Loudscope cannot measure sound right now. You can allow access from your browser's site settings, then try again.
This browser does not support microphone access for web pages, so Loudscope cannot run here. Try a recent version of Chrome, Firefox, Edge, or Safari.
Readings are an estimate based on your device's built-in microphone, which is not calibrated for acoustic measurement. Treat the number as a useful guide, not a lab-grade instrument.
| dB | Roughly like |
|---|---|
| 20–30 | A whisper, a quiet library |
| 40–50 | A quiet room, soft rainfall |
| 60–70 | Normal conversation, an office |
| 70–85 | Busy traffic, a vacuum cleaner |
| 85–100 | A concert, heavy machinery |
| 100+ | Very loud — limit how long you stay this close |
