What kind of work affects hearing?

When a person is in a noisy environment for a short time, even if he leaves the noisy environment, his ears will cause a short-term hearing loss, but when returning to a quiet environment, it can recover in a short time.If you work unprotected in a strong noise environment for many years, the recovery of hearing sensitivity will be prolonged after leaving the noise environment. After several hours or ten hours, hearing can be restored.This kind of hearing loss is called hearing fatigue.As hearing fatigue worsens, auditory function recovery will be incomplete.
