”There is an old man in the family, if there is a treasure.” But have you ever found that the elderly at home old can not hear what you say, and communication is becoming increasingly difficult? The elderly old people can not hear the ear-splitting cell phone ringing, which may be caused by the elderly hearing decline! Many seniors and their offspring think that it is normal to have deaf ears at an older age and ignore it. In fact, elderly people with hearing loss should have their hearing tested, and those with mild to moderate hearing loss should wear appropriate hearing aids as early as possible, and they can also take medication to slow down their hearing loss. 20 million elderly people are deaf in China China has entered an aging society: as of the end of 2012, there were 185 million people over the age of 60 in China! Among the diseases related to aging, diseases with obvious somatic dysfunction are valued, but others, such as senile deafness, have long been neglected by doctors and patients. According to statistics, currently 11% of the elderly over 60 years old in China have hearing loss (deafness), about 20 million people; among the deaf elderly, those with moderate to severe deafness (hearing loss) account for 35%, about 7 million! Dr. Pena Wu, chief physician of the Department of Otolaryngology of Guangdong Provincial People’s Hospital, told reporters that the symmetrical, slowly progressive sensorineural hearing loss in both ears due to aging and degeneration of the auditory organs caused by aging is senile deafness. Most of the hearing loss of senile deafness is mainly high frequency hearing loss, speech recognition ability is significantly reduced, and may be accompanied by tinnitus and vertigo and other symptoms. Although the cause of age-related deafness is not yet clear, in addition to the natural aging of the auditory system, it is usually associated with genetic factors (which predispose the auditory system to damage), atherosclerosis (which leads to blockage of micro-arteries in the cochlea), excessive intake of saturated fatty acids (which aggravates atherosclerosis), diabetes (which leads to endothelial proliferation in the cochlea and reduces blood supply), smoking (which aggravates atherosclerosis), noise and deafness. sclerosis), noise and ototoxic drugs. At this level, age-related deafness is also associated with “affluenza”. Experts also point out that high blood pressure and diabetes are “diseases of affluence” that accelerate hearing loss. “The hearing loss is generally 0.6dB per year after the age of 60. “However, if the hearing loss is combined with hypertension and diabetes, the hearing loss will be accelerated. This is because hypertension and diabetes increase the concentration of blood, leading to blockage of the micro-artery of the cochlea and affecting the blood circulation in the inner ear. Because of the irreversible nature of age-related deafness, hearing aids are the most commonly used hearing aids. However, hearing aids are not suitable for all people with hearing loss. Pena Wu points out that it is important to choose the ones with good performance according to different situations so that the more you wear them, the more deaf you will become. “Some deafness is mainly low frequency hearing loss, can’t hear low frequency sound, if the hearing aid purchased only amplifies high frequency sound, the wearer will still have trouble hearing; while some deafness is mainly high frequency steep drop, that is, can’t hear high frequency sound; some belong to flat type, can’t hear the daily volume, must choose the right hearing aid according to different deafness types. “
