1, which is prone to hearing fatigue in a short time in a noisy environment. Excessive acoustic stimulation of auditory organs will damage hair cells of spiral organs. Even if you leave the noisy environment immediately, your ears will still hum in a quiet environment, covering up your true hearing. This kind of hearing loss is called temporary threshold shift. After a period of time, your tinnitus will disappear and your hearing will gradually recover.
2. Being in a strong noise environment for a long time is prone to permanent hearing loss. The hair cells of spiral organ are often strongly stimulated, which will cause the destruction and degenerative changes of hair cells and cause obvious irreversible sensorineural deafness. This permanent threshold shift is called noise-induced hearing loss.
3, sudden explosion is easy to form explosive deafness. Under the sudden explosion or strong sound stimulation, powerful air shock waves and noise sound pressure waves cause damage to the tissues of the middle ear and the inner ear, and cause hearing impairment within a few minutes, which is called explosive deafness.
