Age-related deafness refers to hearing loss caused by aging and degenerative changes in the auditory system. The hearing organs begin to age after middle age, and hearing loss averages 1.5 dB per year over the age of 40. However, the age of onset and rate of development of senile deafness varies from person to person and is related to genetic factors and the exposure of the organism to various harmful factors in the internal and external environment. The pathological basis of senile deafness is not in the middle ear, but in the cochlea and the entire auditory system above it. It is a degenerative change of the auditory organs triggered by the aging process of the human body. Chronic diseases such as hypertension, vascular sclerosis, diabetes, and coronary heart disease can induce or aggravate hearing impairment. Age-related deafness is related to multiple factors such as noise, lifestyle habits, and genetics. The population distribution of senile deafness has the following characteristics: the incidence of senile deafness is higher in urban than in rural areas; the incidence of senile deafness is higher in those who are engaged in industrial production than in agricultural production; the incidence of senile deafness is also higher in those who have cardiovascular diseases. Therefore, the elderly should pay special attention to the following: quit smoking and avoid alcohol; strengthen exercise; eat a reasonable diet, avoid eating too sweet, too salty and fatty products, especially avoid high fat and high cholesterol diet; pay attention to the treatment of chronic diseases: hypertension, coronary heart disease, diabetes, chronic bronchitis, etc. Once middle-aged and elderly people find hearing loss, they should go to the hospital for examination in time to identify the cause and determine the nature of the lesion for early treatment to prevent the aggravation of deafness. If the high frequency hearing threshold is found to be decreased after examination in a specialized hospital, drugs such as cholesterol-lowering drugs and vasodilators should be taken under the strict guidance of a doctor, and if the hearing loss cannot be recovered, hearing aids can be chosen.
