What is the cause of noise-induced deafness?
Noise-induced deafness, it is sensorineural deafness, because the noise environment is too long and the sound is too loud, causing damage to the inner cochlea and hearing loss.Noise-induced hearing loss is when the patient’s hearing loss is caused by exposure depending on the level or duration of the exposure, which may be temporary or permanent hearing loss.Its frequency drops, especially high-frequency hearing loss (especially 3-6kHz) hearing threshold increases.
First of all, it is to clarify the reason. The noise environment is too long and the sound is too loud. First of all, it is caused by work in the occupational environment. Occupational relationship damage. Frequently, strong noises such as chain saws, internal combustion engines, pumps or airplane noise can damage the inner ear.Activities such as shooting, snowmobiles, flying, and diamonds are often associated with deafness caused by noise.Exposure to strong noise causes the hair cells of the inner ear to disappear.Although the sensitivity of individuals to noise-induced deafness varies greatly, if they are exposed to enough intensity for a sufficient period of time, almost everyone’s hearing will be impaired. Any noise over 85dB is destructive.With the continuous enhancement of occupational protection work, the proportion of noise-induced deafness caused by occupational factors has gradually decreased.
但现在由于年青年人喜欢用耳机大声听音乐，在就是到一下迪厅及KTV环境，声音非常大，寻找各种声音刺激 引起非职业性逐渐增加。当噪声超过85～90dB强度时，即对耳蜗造成损害，在就是有的人个体易感，才容易受损。当接触时间过长，在就是距离噪音过近，就很容易引起噪声性耳聋。噪声性耳聋，它没有好的治疗方法，主要就是预防，首先就是建议青少年最好不要过多用耳机听音乐，音乐声音不要过大。在就是避免到一下声音大娱乐场所。国外对青少年做一些“危险分贝”教育，1.教育孩子知道危险声音来源是什么；2.暴露于危险声音的后果是什么；3.我如何可以自己免于危险声音。
