According to the NIH1990 year, the proportion of noise-induced hearing impairment in adult hearing impairment is as high as one-third or more. These people are mostly engaged in manufacturing, farm, garden, construction, mining and transportation. However, most of the workers who work in these jobs go to the doctors until they have serious disabilities in their retirement or hearing. This often causes irreversible hearing impairment.

The effect of noise on hearing is varied. When the noise intensity is low, it does not affect normal communication. This situation generally does not cause permanent damage to the auditory system; but when the noise intensity is high, it will lead to temporary Sexual hearing loss, which can persist for a period of time after the noise has ceased, and when it exceeds a critical level, it can cause damage to the internal structure of the cochlea and cause permanent hearing loss.

There are three main methods for reducing noise in industrial production. The most effective technology is noise reduction, which is controlled by scientific and technical means from the source of noise generation. However, this method is costly. In the case that industrial enterprises cannot pay attention to technical noise reduction, the second method is often adopted. Noise exposure time. This method is used by many high-automation industrial enterprises because of its low cost. However, in the environment of non-highly automated enterprises, it is difficult to achieve a rotation system, and enterprises are not willing to let skilled workers leave the workbench due to noise damage.

The third and most common method of noise reduction is the use of personal hearing protection. Including earmuffs, ordinary plug-in earplugs, custom-made ear molds, etc. This method requires the workers to truly master the correct method of wearing protective equipment, otherwise it will cause noise-induced hearing loss.

In addition, people who work in a noisy environment for a long time should develop a habit of regularly checking their hearing, just like regular physical examinations, and avoiding their own hearing health when avoiding irreversible hearing loss.
