SoundMeter - Decibel Meter

SoundMeter is a practical decibel meter and sound level meter for measuring, recording, and analyzing everyday noise. Use your phone to check real-time sound levels, track changes, and save measurements from different places and situations.

Whether you're checking noise at home, in the office, in public spaces, or around traffic and construction, SoundMeter helps you understand your surroundings and keep track of sound levels over time.

【Live Decibel Meter】

Start measuring with one tap. View real-time A-weighted sound levels in dB, including current, maximum, minimum, and average readings. A live waveform makes changes in sound levels easy to follow.

Switch between Fast and Slow time weighting, and set a decibel threshold to receive vibration alerts when the sound level exceeds your chosen limit.

【Decibel Camera】

Take photos and record videos with live decibel readings and sound statistics displayed on the screen.

Save photos and videos with decibel watermarks to document environmental noise, construction sounds, or changes before and after soundproofing improvements.

【Measurement History & Trends】

Automatically save measurement sessions with duration, location, maximum and minimum levels, and sound trends.

Replay saved audio recordings, preview waveforms, and rename your sessions to keep your measurements organized.

【Microphone Calibration】

Adjust your phone's microphone calibration settings. Use a trusted sound level meter as a reference to help account for differences between devices.

【Noise Standards & Sound Guide】

Browse published noise standards from multiple countries and regions, along with everyday sound level references to help you understand different noise environments.

【SoundMeter Pro】

Core features, including live measurement, history tracking, the decibel camera, and calibration, are available for free.

Upgrade to SoundMeter Pro to unlock PDF measurement reports, high-quality audio saving, watermark photo downloads, and an ad-free experience.

【Important Notice】

SoundMeter estimates sound levels using your device's microphone. Results may vary depending on your phone's hardware and measurement environment. Readings are intended for everyday reference only and are not a substitute for certified sound level meters, legal measurements, or professional assessments.
