From a physiological point of view, all sounds that disturb people's rest, study and work and that interfere with the sound you hear, i.e. unwanted sounds, are collectively referred to as noise. When noise has adverse effects on people and the surrounding environment, noise pollution is formed; noise pollution is a perceived pollution that does not bring about chemical pollutants, but only harms the human ear due to the sound energy acting on it. The pollution generated by the noise has no after-effect, the sound source stops, the noise disappears, no accumulation phenomenon exists, and no trace is left, but the loss caused by the noise to the hearing and the body health of people is cumulative.
