Industrial noise refers to the noise generated by the operation of mechanical equipment. According to its noise source characteristics, it can be divided into airflow noise, mechanical noise and electromagnetic noise.
Harm of industrial noise:
1, which affects rest and work. During rest, the ambient noise is required to be less than 45dB, and if it is greater than 63.8dB, it is difficult to fall asleep;
2. Damage to auditory organs The adaptability of human auditory organs is limited. Working under strong noise for a long time will cause hearing fatigue and hearing loss;
3. Noise that causes cardiovascular diseases can make sympathetic nerves nervous, which is manifested by accelerated heartbeat, arrhythmia, blood pressure fluctuation and positive increase of ECG test;
4. The influence of noise on nervous system will cause neurasthenia syndrome, such as headache, dizziness, insomnia, dreaminess and memory loss.
