Why do ears suddenly ring?

The symptoms of tinnitus are caused by chronic noise, fatigue and otitis media.

1. Noise exposure for a

long time or excessive exposure to noise can stimulate the central nervous system of the brain, causing damage to hearing and causing tinnitus.

2. Excessive fatigue

, mental stress and other psychological factors may also affect the body's immune system and blood supply to the brain, thus damaging hearing and causing tinnitus symptoms.

3. Otitis and otitis media

are mostly caused by pathogen infection, disease and other factors. Inflammation stimulates the internal nerves of the middle ear, leading to the destruction of the sound transmission structure.
