Studies have found that noise above 85 decibels can make people feel distracted, people will feel noisy, they will not be able to concentrate on work, and the result will be lower work efficiency. The decibel tester can effectively help you measure the decibel of the surrounding environment and help you stay away from noise troubles Accurate decibel tester 1. Use the self-developed tuning algorithm to accurately monitor the surrounding sound in real time 2. Quantify the decibel number, automatically calculate the noise extreme value decibel recorder 1. The first decibel recorder function, which can identify the volume decibel value in the audio in real time 2. The volume decibel value in the audio can also be displayed in real time during playback Decibel Watermark Camera 1. Take photos for evidence, combined with the decibel recorder to achieve perfect results 2. Decibel watermark The camera can display the decibel size, current position and time on the photo in the form of a watermark, the text supports stepless color change, and can be adapted to photos of any color Studies have found that noise above 85 decibels can make people feel distracted, people will feel noisy, they will not be able to concentrate on work, and the result will be lower work efficiency.
