What are the causes of tinnitus? Pay attention to these four points

Tinnitus most commonly occurs in the elderly. Generally speaking, after discovering that people suffer from tinnitus, they should learn more about the causes of tinnitus. So, what are the causes of tinnitus?

noise:

People have a common experience that if they suddenly hear the sound of firecrackers, there will be a long echo in the ears, which will take half a day to subside. This is because the external noise temporarily damages the auditory nerve. Those who work in a noisy environment for a long time are victims of noise. Long-term noise stimulation often causes damage to the inner ear nerves. Noise-induced tinnitus is mainly manifested as a disorder of the spontaneous activity of auditory nerve fibers.

Ototoxic drugs:

Drugs that cause tinnitus are divided into two categories. One type of drugs only causes tinnitus without causing hearing loss. The reason is that this type of drug affects the metabolic process of biogenic amines related to neurotransmitters in the central nervous system, causing "convulsion" side effects of the auditory central neurons.

External and middle ear diseases:

Foreign objects in the external ear (earwax) may cause tinnitus when they touch the eardrum; vascular malformations and lesions in the middle ear may also cause tinnitus. Most of this type of tinnitus can be cured through examination and treatment by an otolaryngologist.

age:

The incidence of tinnitus in people over 60 years old is as high as 30%. The main reason is the degeneration of the auditory nervous system as people age.
