Are deafness first tinnitus?
The effect of noise on the auditory organs can be roughly divided into two situations: one is the occurrence of hearing fatigue in a noisy environment. Because the auditory organs are stimulated by sound, the body will inevitably respond appropriately. However, when this stimulus is too strong, such as90Decibels can damage the auditory organs, that is, the hair cells that damage the auger. At this time, even if you leave the noisy environment, in the quiet place, the ear will still squeak. This kind of tinnitus in turn conceals the hearing. At this time, if you talk to someone, you will not hear what the other person loves to say. After a while, the tinnitus disappeared and the hearing was restored. This is the phenomenon of hearing fatigue.
In another case, when working in a strong noise environment for a long time, the hair cells of the auger are often exposed to noise, which causes hair cell destruction and degenerative changes. The degree of disease is closely related to the intensity, frequency and length of service of noise.
Noise deafness has more and more trends in modern society. It used to be concentrated in some special industries. However, nowadays, as more and more young people put their headphones on their ears, this kind of deafness will follow the dynamic The rhythm keeps moving forward. Some people will ask, I am listening to music, not noise, how can I get noise deafness? In fact, the noise is relative. If the music is mixed with sounds of various frequencies, such as high-pitched rock music, it will cause ear damage when listening for a long time.
