## What is Decibel Meter Noise Detector?

The decibel tester is a professional noise decibel detection software, also known as a decibel measuring instrument, decibel meter, noise detector, etc. It can help you detect the decibel (dB) of the surrounding environment in real time, allowing you to understand the noise situation of the surrounding environment at any time, easily measure the current noise level of the environment, record the decibel change value, capture the surrounding environment, and record the noise. Easy to operate and convenient to use.

[Functional Features]:
1. Real time decibel detection: Measure the decibel value (dB) of the current environment's noise, synchronously record audio and mark the peak decibel value, and save the generated timestamp record.
2. Multimedia evidence collection: Record decibel data watermarks during photo and video evidence collection, with a complete and traceable evidence chain, and support for adding evidence collection information such as geographic location and time.
3. Real time chart display: The chart displays real-time changes in noise decibels and provides reference for noise standards.
4. Historical record viewing: Record the decibel level of each detected noise, making it convenient for you to view the detection history.
5. Test result export: One click generation of data detection report, supports exporting and saving to local.

Usage tips:
The values obtained by the decibel meter are for user reference and simple recording only. The noise value results come from the user's native mobile phone microphone, and the microphone of mobile devices has certain limitations in recording, so obtaining values cannot replace professional noise instruments.
