2、 Introduction to indoor noise decibel transmitter

Noise is the sound produced by a sound generator when it undergoes irregular vibrations. In this sense, there are many sources of noise, such as the sound of cars on the street, the sound of voices in a quiet library, the sound of machines on a construction site, and the loud sound of neighbors' televisions, all of which are considered noise. Excessive noise can disrupt people's normal rest, study, and work, as well as interfere with the sounds they want to hear.
