Measure Sound Levels Online — Free Decibel (dB) Meter for Your Mic

The Sound Level Meter measures how loud your environment actually is, in decibels (dB), using your microphone. Click Start Measuring and you'll see a live dB reading update as the sound around you changes — from a quiet room at 30 dB to a noisy office pushing 70. Good to know before you record a podcast or join a call and discover the AC unit was louder than you the whole time.
