DeciBell

DeciBell is a simple sound level meter that helps you monitor noise around you in real time.
Use the live circular gauge to see the current dB level, watch the color change from quiet to danger, and track session stats including minimum, average, and maximum sound levels. A scrolling waveform gives you a quick visual feel for how the sound changes over time.
Features:
- Real-time sound level measurement
- Large dB gauge with dynamic color levels
- Quiet, Moderate, Loud, and Danger indicators
- MIN / AVG / MAX statistics for each session
- Live waveform visualization
- Saved session history with date, duration, average dB, and maximum dB
- Common sound reference list
- Noise alert threshold setting
- Auto-stop options
- Dark and light theme support
The app uses your microphone only while measuring sound. Measurements are intended for everyday awareness and may vary depending on your device microphone and environment. DeciBell is not a replacement for a calibrated professional sound meter.
