The relationship between noise deafness and tinnitus

After the occurrence of noise deafness, the earliest symptom is tinnitus. Tinnitus is often more common than deafness, especially high-pitched tinnitus.

The effect of noise on the auditory organs can be roughly divided into two situations: one is auditory fatigue in a noisy environment. Because the auditory organs are stimulated by the sound, the body will inevitably respond appropriately. However, when the stimulus is too strong, such as90Decibels can damage the auditory organs, which destroy the hair cells of the auger. At this time, even in a quiet place, the ear will squeak in a quiet place. This tinnitus will cover our hearing. If you talk to someone, you will feel that you can’t hear what the other person is saying. After a while, the tinnitus disappeared and the hearing resumed. This is the phenomenon of hearing fatigue.

In another case, when working in a long-time, strong-noise environment, the hair cells of the auger are often stimulated by noise, resulting in destruction of hair cells and degradation of hair cells. The extent of the lesion is closely related to noise intensity, frequency and service time.

Because the first to be affected is the high frequency outside the language frequency, this is the frequency that is not commonly used in life conversations. Therefore, in the usual language conversation, I don’t feel that listening is not good. After a few years, it will gradually develop into a hearing loss of speech frequency, and will gradually feel deaf.
