About Decibel Tester-Noise Testing
The decibel testing app can provide you with noise detection references anytime and anywhere, along with location information of the measurement points. You can also export audio files for sharing at any time.
Although we provide the most accurate measurement data possible, this app still cannot completely replace professional measurement equipment and is strictly intended for personal reference.
