1. Prevention of acoustically deafening
Acoustic impairment deafness refers to damage to hearing organs caused by sound. According to the nature of the sound that causes damage, it can be divided into knocking deafness and noise deafness. Noise trauma is extremely common in modern society and has been regarded as one of the seven major public hazards worldwide.
1. Acute Acoustic Deafness
It is damage to the hearing organs caused by a sudden strong explosion or sound. It is commonly used in wars and various explosive operations. Such as engaged in mining, quarrying, construction and other construction. Some unexpected explosions in life, such as boilers, gas tanks, pressure cookers, and televisions and refrigerators in household appliances, are occasionally seen in natural explosions.
prevention

Breathing with an open mouth can reduce the degree of injury.
2. Chronic acoustic loss deafness
It is hearing loss caused by a long-term exposure to noise stimulation, also known as noise-induced deafness. Deafness caused by noise from production operations is called occupational deafness. Its occurrence is closely related to the intensity, nature, exposure time, vibration in the environment, and the age and constitution of the patient.
In order to prevent noise-induced deafness, the following measures should be taken.
(1) Reduce the noise intensity
(2) Reduce the conducted sound intensity
(3) Reduce exposure time
(4) Use of ear protectors
