dB Pulse: Decibel Meter

dB Pulse estimates sound levels locally using your microphone. View A/Z weighting, Fast/Slow response, Leq, peak hold and a rolling 60-second graph.

- Choose an input device and adjust its calibration offset.
- Set sustained-noise alerts and follow daily NIOSH-style noise dose.
- Save session summaries locally and export CSV or PDF.
- Use the tone generator, speaker test, white/pink/brown noise, decibel calculator and dose calculator.

The app is free, with no ads or account. Microphone audio is processed on your device; it is not recorded or uploaded. Snap Store manages updates.

Readings are estimates until calibrated against a trusted reference. This is not a certified sound level meter or a safety determination.
