About this app
The decibel tester App can provide you with noise detection reference anytime, anywhere, and also provide detection point location information. You can also export audio files for sharing at any time. Although we provide as accurate measurement data as possible, this App still cannot completely replace professional measurement equipment and is tightly used for private reference.
