Sound Decibel Meter Online

Sound Decibel Meter Online is a free, browser-based tool that provides live decibel readings using your device's microphone. It offers real-time measurement of current, minimum, average, maximum, and peak dB levels, along with a visual chart and color-coded gauge. The tool processes audio locally via the Web Audio API, ensuring privacy as no audio is recorded or uploaded. Key features include calibration offset adjustment, a noise reference chart, and support for multiple languages. Ideal for quick ambient noise checks in rooms, offices, or outdoor environments, it serves as a convenient alternative to dedicated sound level meters for non-critical applications.
