Among China’s huge population base, there is a special group, namely the hearing loss population, which is our top priority. It is predicted that the total number of people over the age of 5 with hearing loss will increase year by year, and by the end of 2050, there will be approximately 290 million people, and those over the age of 70 will account for approximately 200 million.

Long-term tinnitus and loud TV sound but still unclear hearing are all possible early manifestations of presbycusis. . 80% of elderly people do not receive any intervention after hearing damage occurs, eventually leading to deafness. Therefore, early intervention and treatment for the elderly to preserve their remaining hearing is very important to improve their quality of life in their later years.

Deafness in the elderly will make them more lonely, cause psychological trauma, slow reaction and mental decline. Research shows that presbycusis is positively correlated with brain atrophy and Alzheimer's disease. With hearing loss and disuse of hearing function, atrophy may be aggravated and Alzheimer's disease may come early.
