Standard noise decibel detector is a mobile phone software that can measure noise for free. It can provide professional-level measurement results and is calibrated with a real Nor140 high-precision decibel meter. With it, you can measure the noise level of your environment, save the measurement results and location, and share the measurement results with others. In addition to measuring noise, it also has the functions of calculating area, measuring angle, speed and altitude.
Features:
1. Decibel measurement: measure the decibel level of environmental noise through the microphone of the mobile phone
2. Quickly detect noise changes and display the index range in real time: start the test with one click, quickly display the test results, and watch the trend in the form of a waveform graph
3. Save the test noise record, high-definition recording lossless playback: save the previous noise record sound, recall the playback at any time to judge the environmental noise
4. According to the detected value, refer to the noise decibel reference table to judge whether the current sound is noise. If it is too high, you need to stay away in time
5. Various measurement tools such as measuring area, angle, speed, altitude, etc. can meet your needs at any time
#Suitable for the crowd#
- In schools and offices, check whether there is excessive noise pollution around the office area and whether the office environment is qualified.
-Used for noise detection and testing in public places such as job sites and squares.
- Sensitive to sound, especially noise-induced insomnia, want to know the decibel level of environmental noise
- During travel, some areas with excessive noise cannot be avoided during travel. After real-time detection, you can stay away from polluted environments
