Tips: How to prevent noise?

Noise is widely present in production and work environments. Noise can cause harm to many human systems, such as nerves, cardiovascular, endocrine, and digestive systems, but the major and specific injuries are in auditory organs.

Noise is one of the common occupational diseases. It refers to a type of auditory hearing impairment that occurs when people are exposed to productive noise during the course of their work. Factors that contribute to occupational noise are: intensity, time, frequency and spectrum of contact noise, individual sensitivity, and noise age.

The main measures to prevent noise are:

1. Source control: Eliminating sound sources, reducing sound intensity, and limiting sound propagation.

2. Occupational Health Check: The workers who work in a noisy environment are subject to an employment examination, and the auditory records are established in the occupational files. The exposed workers are also required to conduct regular medical examinations so that the noise sensitive persons and early hearing-impaired persons can be found in time.

3. Strengthen personal hearing protection measures, work in a noisy environment and wear appropriate personal hearing protection products, such as: anti-sound earplugs, earmuffs or soundproof caps. (Source: Tianjin Center for Disease Control and Prevention)
