If the elderly are exposed to various noises such as the roar of machines, the noise of the workshop, and the noise of human voices for a long time, the tiny blood vessels of the inner ear will often be in a state of spasm, the blood supply of the inner ear will be reduced, the hearing loss will be sharply reduced, and even noise-induced deafness will be caused.Therefore, avoiding or reducing noise interference as much as possible is the first priority for the elderly to protect their hearing.If the elderly are often in a state of irritability and irritation, the autonomic nerves in the body will lose their normal regulatory functions, causing ischemia, edema and hearing impairment in the inner ear organs, which are prone to severe hearing loss or sudden deafness.Therefore, the elderly should try to keep themselves relaxed and happy.
