About this app

The environmental noise decibel tester can also be called a decibel meter, sound meter, noise meter, noise detector. It uses the mobile phone microphone to detect the surrounding environment and white noise in real time. After the test, it will display the current environmental noise decibel value, The location information is used to determine whether there is noise pollution in the current environment based on the noise level and reference examples. It is a simple and practical tool for noise detection.
Our lives are surrounded by various noises, among which the harm caused by noise cannot be ignored. We need a professional noise detection software to visualize the noise decibels, which can not only measure the sound decibels of the current environment in real time, but also Let you know if it will harm human health, so you can stay away from the noise environment in time.

【Application Features】
#Locating environmental noise test, high-precision noise detection: accurate form of the current environment decibel value (DB), real-time display of the current value as the environment changes
#Quick detection of noise changes, real-time display of the index range: one-click to start the test, quickly display the test results, and watch the trend in the form of a waveform graph
#Waveform visual display, maximum/minimum/equal decibel value: visual display of change trend, record maximum, minimum and average value, multiple data records
#Save the test noise record, review important information at any time: save the previous noise record sound, call it at any time to judge the environmental noise situation
#Noise level reference example, stay away from noise hazards in time: According to the detected value, refer to the noise level example to determine whether the current sound is noise, if it is too high, stay away in time

[Application scenario]
1. Use in the residential area and bedroom to determine whether there is noise in the current environment and whether it is helpful for sleep
2. In schools and offices, check whether there is excessive noise pollution around the office area and whether the office environment is qualified
3. In public places such as squares, noise pollution is one of the environmental pollutions that have a greater impact. Higher decibel noise can even cause serious damage to the eardrum of a person, causing deafness, etc.
4. During the trip, some areas with excessive noise cannot be avoided during the travel, and after real-time detection, you can stay away from the polluted environment

【Instructions】
1. Click the "start" button on the main page to immediately detect the current environmental noise
2. Real-time display of the noise decibel value of the current environment, observing the waveform diagram can know the change of noise
3. Display the maximum and minimum average values ​​of the current test results, and see the reference examples to determine the current noise level
4. Click Save to save the currently recorded data for review
5. Click the history record, the sound measurement record saved before, to judge the measurement result
