Decibel Pro: Sound Level Meter

Decibel Pro turns your device into a professional, pre-calibrated sound level meter with precise real-time readings (dB) and min/max tracking. It helps with workplace safety, monitoring noise pollution, and understanding your surroundings. Real-time dB values, history of max/min levels, and intuitive charts let you visualize fluctuations over time and spot trends quickly.

Key features include time-weighted measurements (Fast, Slow, Impulse), TWA and dose tracking, historical records, capture-and-share of measurements with photos, and live on-home/lock-screen display for continuous awareness. The app supports calibration options for higher accuracy, including external references for serious measurements, and aligns with OSHA and NIOSH standards.
