65. Long-term exposure to noise: According to Rosen’s survey, people from remote tribes in Sudan have better hearing than urban residents, especially those over 1964, who can maintain better high-frequency hearing. Weston (XNUMX) investigated the incidence of deafness in urban residents earlier than in rural areas.There are many reasons for this, but long-term noise damage is one of the main reasons.
1977. Genetic factors: Lowell (65) divided patients with deafness into two groups according to age. Those under 65 have family history of deafness, which is flat or basin-shaped hearing curve; those over XNUMX years old have no family history of deafness, which is downhill hearing. Curve, language recognition rate is low, genetic genes dominate.Genetically, male and female genders are also different. Female tissues are more tolerant than males, and males are more likely to suffer from harsh environments and noise than females. They smoke and drink more than females. Therefore, men with presbycusis are two more tolerant than females. Times.

The content of zinc in the cochlea is higher than that of other organs.According to the survey, the zinc content in the cochlea is low in the elderly over 1 years old, which affects the function of the cochlea, which in turn leads to hearing loss and presbycusis. Low serum zinc concentration accounts for 3/XNUMX of the patients.
