The global hearing disability data released by the World Health Organization (WHO) shows that about l/3 of the elderly population over 65 years of age have hearing disability. A study conducted by Chinese scholars with WHO program in Su, Sichuan, Qian and Ji provinces showed that the prevalence of hearing loss in the elderly population over 60 years old was as high as 59.5% and the prevalence of hearing disability was 26.6%. In other words, more than 1/4 of the elderly population over 60 years old in China are hearing disabled. Hearing-impaired elderly people often call dinner, can not hear; answer the phone, inaudible; watch TV, the volume is turned up; talk love to interrupt, bullheaded; hearing, but also very afraid of noise, in a noisy environment and communication with people more difficult, sometimes become more and more isolated ……. These are the performance of senile hearing loss, be alert! A, people old deafness is not natural Many families or older people think: the elderly poor hearing is “natural” thing, let it develop, do not care about it, this view is very wrong. Although physiologically speaking, hearing will gradually decline with age, and generally after the age of 60, there will be mild (mainly high frequency) hearing loss. However, the first cause of hearing loss in the elderly is actually not a physiological decline, but a pathological change that damages the auditory system by two major factors: genetics and environment. Therefore, it is important to actively prevent and treat these factors rather than leaving them unattended. However, it is possible to avoid noise, use ototoxic drugs, and actively prevent and treat systemic diseases that affect hearing, such as diabetes, hypertension, arteriosclerosis, kidney disease, and autoimmune diseases. Early therapeutic intervention for elderly people with hearing loss can preserve residual hearing and prevent further hearing damage. Preservation of residual hearing is very important to improve the quality of life of the elderly in their later years. It is important to have early ear, hearing and related systemic examinations after the onset of early symptoms to allow for timely intervention and treatment. Some people develop hearing loss in their 40s and 50s, therefore, prevention should start from middle-aged and young people, paying attention to general health and environmental hygiene. Second, poor hearing caused by the “butterfly effect” hearing and language is an important means of human communication and understanding of the world, ear disease and hearing impairment of the haze of human, seriously hampering people’s communication, which leads to cognitive, emotional and social behavior disorders. It can reduce the quality of life and work, and can be complicated by a series of problems such as depression, loneliness, anxiety, and fatigue, which not only endanger individuals and affect families, but also involve society, making it a priority for prevention and control of the global disease burden. This “butterfly effect”, which is caused by a small disturbance in the ear and leads to huge changes in individuals, families and even society, must attract the attention of the whole society. Since the incidence of hearing loss in the elderly is the highest, the prevention and control of this “butterfly effect” has become a top priority. Therefore, once the elderly hearing loss is found, family members should encourage and accompany the elderly to the hospital to identify the cause and actively intervene. The vast majority of hearing loss in the elderly is sensorineural hearing loss, and so far there is no specific medicine to cure it, but there is nothing we can do. The scientific fitting of hearing aids, cochlear implants, specialized hearing and speech rehabilitation training, the application of auditory aids and the improvement of the listening acoustic environment are all effective solutions to hearing impairment. Hearing aids can match and compensate by amplifying different frequencies and different intensities of sound in a targeted manner according to the hearing loss; at the same time, they can limit and compress excessive sound according to the affected ear’s tolerance to loud sounds, and strive to hear, hear clearly and hear comfortably. Therefore, for most elderly people with hearing impairment, hearing aids can improve their hearing, communicate better with others, and prevent further hearing degradation due to the principle of “use in and use out”, which is the preferred measure. Due to the rapid development of digital and electroacoustic technology, modern hearing aids can meet the needs of most people with hearing loss. However, due to the complexity of hearing impairment and individual differences, hearing aids must be scientifically fitted according to the characteristics of the affected ear in order to be effective, and should not be purchased casually. China has introduced the national occupational standard “hearing aid dispenser” in 2008, and there is a national vocational qualification training and examination system. It is recommended that when purchasing hearing aids, you should choose a qualified dispenser at a hearing aid store. In addition, after the fitting, there is a rehabilitation process of adaptation, debugging and adaptation again, which cannot be done overnight. In short, hearing disability seriously affects the physical and mental health of the elderly, not only leads to communication barriers, but also causes a variety of psychological problems, which greatly impairs the quality of life of the elderly and their family and social functions. Therefore, it is very important to do a good job of hearing health care for the elderly.
