Online Decibel Meter

Online Decibel Meter is a browser-based tool that measures approximate sound levels through your device's microphone. It displays real-time decibel readings with live graphs, peak level tracking, and average sound calculations. The tool includes calibration settings, weighting filters, and a noise floor indicator to help users understand sound intensity across different environments.

Designed for general awareness and educational purposes, it shows how various everyday sounds compare on the decibel scale—from quiet environments to dangerous noise levels. The maker notes it was built with Lovable. The tool includes clear disclaimers that it provides estimates only and is not suitable for professional, legal, or workplace safety applications.
