Decibel : dB sound level meter

Decibel turns your device into a powerful sound level meter without any extra hardware. Measure ambient noise in real time, monitor sound levels (dB), and explore frequencies with the built-in Spectrum Analyzer. Capture reliable sound and noise data wherever you are. Designed for casual users, audio enthusiasts, and sound engineers, Decibel works as a portable sound meter for quick sound checks or deeper audio analysis. Use it to easily check noise levels, test room acoustics, monitor workplace noise, or fine-tune audio equipment. Decibel has various advanced features, including saving and exporting noise measurement data, live sound level overlays for photos and videos, and exporting data to the Health app to track noise exposure over time. “The best way to meter sound levels” — AppAdvice SLEEP TRACKING AND SOUND RECOGNITION Decibel’s sleep tracking and smart sound recognition help you understand your sleep environment and nighttime noise. While sleep tracking is active, the app can detect common sleep sounds such as snoring, coughing, talking, and other household or environmental noise that may affect sleep quality. Each detected sound appears on a detailed sleep timeline, so you can see exactly when disruptions occurred and play back the related audio. This makes it easier to identify snoring patterns, sleep disturbances, and noise events that impact your rest. All sleep sound recognition and audio analysis are performed entirely on your device using advanced on-device machine learning. Recordings stay private, are processed locally, and never leave your device.
