Sound meter - dB meter

The Sound Meter Chrome extension transforms your device into a professional digital sound level meter for measuring environmental noise in decibels (dB). It offers a simple, intuitive interface displaying real-time minimum, average, and maximum dB values along with a graph visualizing the noise data.

Users can calibrate the tool for precise measurements and reference common noise levels ranging from a quiet library (30-40 dB) to loud sounds like thunder or sirens (120-140 dB). While optimized for typical voice-range sounds, it's a handy auxiliary tool to assess noise at home, in the office, or outdoors. For extremely accurate results over 90 dB, a dedicated sound level meter is recommended.
