About the startup
Measure environmental noise, test speakers, microphones and headphones, generate tones, and analyze sound frequencies directly in your browser. Decibel Meter Lab is a free browser-based audio toolkit for measuring, testing, and understanding sound without installing software or creating an account. Users can check environmental noise with the online decibel meter, test speakers and stereo channels, evaluate microphones and headphones, generate tones and frequency sweeps, inspect bass and subwoofer performance, and analyze sound with a real-time spectrum analyzer and spectrogram. The platform is useful for students, musicians, creators, educators, home-studio users, audio enthusiasts, and anyone troubleshooting everyday audio equipment. Most processing happens directly in the browser for quick and private access. Because consumer microphones are not professionally calibrated, sound-level readings are presented as practical estimates rather than certified SPL measurements.
