Decibel Meter measures ambient noise with pre-calibrated dB readings, so you always know exactly how loud your surroundings are — at home, at work, at concerts, or on the go. Protect your hearing, monitor noisy environments, and finally understand the sound around you. Whether you are checking workplace noise, improving room acoustics, monitoring environmental noise pollution, or tuning audio systems, this app provides fast, reliable sound level measurements in dBA, dBC, and dBZ. WHAT MAKES IT GREAT - Trusted accuracy: pre-calibrated for iPhone and iPad, with built-in microphone calibration tools for improved precision - Real-time measurement: decibel (dB) readings update continuously, with A, C, and Z frequency weighting (dBA, dBC, dBZ) - Response modes: FAST, SLOW, and IMPULSE with real-time average (Leq) and peak detection - Spectrum Analyzer: real-time FFT, spectrogram, and octave-band visualization for audio analysis and acoustic tuning - Noise Dosimeter: daily noise exposure estimates based on NIOSH & OSHA standards - Long-term tracking: save measurement history with timestamps and review historical logs - Export & share: export detailed PDF reports and share results instantly - Accurate frequency detection for sound analysis, audio diagnostics, and equipment tuning - Beautiful, intuitive UI with digital and analog displays TECHNICAL SPECS - Measurement range: 30–130 dBA - Response time: SLOW (500 ms), FAST (200 ms), IMPULSE (50 ms) - MIC gain offset: -50 dB to +50 dB - Real-time current, average (Leq), and max values with digital & analog displays USE CASES Noise measurement, environmental noise monitoring, home cinema calibration, room acoustics, workplace safety, and audio testing. PRIVACY All audio processing is performed locally on your device. No recordings or sound data are uploaded or shared. NOTES - An average quiet room reads about 30 dBA; the 30–130 dBA range is the standard usable range. - For professional use, custom calibration with a reference device is recommended. - This app is for reference and educational purposes only. It is not a replacement for certified professional acoustic measurement equipment. Accuracy may vary depending on device hardware and microphone quality.
