Hearing aids are best worn in both ears
According to the World Health Organization (2018), people with hearing impairment account for about 5% of the total population. According to the current population of 1.39 billion in China, there are about 70 million people with hearing disabilities in China. The number of elderly people over the age of 60 in China is about 210 million, of which more than 30% suffer from hearing impairment, and the number of hearing impairment in the elderly is more than 60 million.
Most of the hearing impairment in the elderly is senility deafness. The hearing loss cannot be recovered by drugs or surgery. Most of them can be used to improve the auditory effect and improve the quality of life through the use of hearing aids.
Is the hearing aid like a commodity, just buy one?
Older people often understand and touch hearing aids by watching advertisements or buying them on the market. It feels like a hearing aid can be amplified. But after using it, I feel that the noise is too loud to bear; I can't hear what I want to hear, and I have a headache when I don't want to hear what I want to hear, so they will say "the hearing aid has no effect." But they ignore a very important question: hearing aids are not ordinary goods and cannot be purchased at will. The choice of hearing aid requires professional inspection, fitting, guidance and rehabilitation. When the elderly experience hearing loss, they should go to a professional medical institution. At the same time, consultation and fitting by a professionally trained and qualified hearing aid fitter are required. Because each person's hearing situation, living environment, and needs are different, the individual differences are relatively large. At the same time, hearing aids require professional debugging, and they can be used directly without being bought. If it is not debugged or debugged inaccurately, it will be counterproductive and affect the existing residual hearing.
Will hearing aids wear more and more deaf?
Many elderly people have long heard of hearing loss, but they are reluctant to use hearing aids. They are worried about wearing more and more deaf, until it becomes severe deafness. They completely affect daily communication and afterlife, and they think that they need to be equipped with hearing aids. The effect of using a hearing aid will be worse.
For patients with hearing loss, wearing a hearing aid does not affect hearing. In general, with the increase of age, the physiological functions of the human body gradually decline, the inner ear hair cells are apoptotic, and the hearing function is decreased. Also, other underlying diseases (such as diabetes, cardiovascular disease, etc.) may also cause hearing loss. Therefore, the progressive decline in hearing of elderly patients has nothing to do with wearing a hearing aid. Without the use of hearing aids, the auditory function, verbal comprehension and brain dysfunction are positive. Studies have shown that hearing loss is directly proportional to the incidence of Alzheimer's disease. Therefore, once hearing loss is found, hearing aids should be used as early as possible to maintain the function of the auditory function and the brain's speech center.
One ear can be heard with hearing aids. Do you still need to wear a binaural hearing aid?
Some older people think that one ear can hear the words, there is no need to wear hearing aids in both ears, and they spend more. But after a long time, I found that the ear that did not wear the hearing aid was getting worse and worse. This phenomenon is called delayed hearing deprivation. We all have two ears, and there are many benefits to using hearing aids in both ears: 1 can distinguish the direction of the sound, to achieve sound source positioning. 2 binaural integration to improve sound and sound. 3 Improve verbal intelligibility in noisy environments and improve signal to noise ratio. 4 Eliminate the cephalometric effect and avoid the decline of verbal intelligibility caused by high frequency attenuation when speech information reaches the contralateral ear. 5 to avoid the occurrence of delayed hearing deprivation. 6 Avoid unilateral hearing fatigue. Since there are so many benefits to using hearing aids in both ears, older people should choose and use hearing aids as soon as they find hearing loss.
Is the more expensive hearing aid the better?
At present, the price range of hearing aids is relatively large, and the price of a hearing aid ranges from three to four thousand to three or four thousand. What is the difference between them? The most important structure in digital hearing aids is digital chips. If the processing speed of digital chips is faster, it will collect more speech signals, and the better the recovery of speech envelopes will sound. The more natural the sound will be, the higher the definition will be, and the ability to reduce noise will be stronger. It can also automatically switch to the corresponding program automatically as the environment changes, to adapt to the hearing impaired, no need to manually switch Programs, such hearing aids will also be relatively expensive.
However, the hearing aids that are not necessarily expensive are adapted to the needs of each individual. The hearing aids should be selected according to their own hearing loss, living habits, and comprehensive factors such as the daily environment. For the elderly, due to the inflexibility of the elderly, it is also necessary to consider the type of hearing aid that is easy to remove and adjust the knob for easy operation.
If you want to listen, wear it again, not usually. Does the hearing aid need to be used all day?
Some elderly people think that hearing aids are very expensive. They are usually reluctant to wear hearing aids. Only when a friend visits or attends important occasions, they wear a hearing aid. In fact, hearing aids are like our ears and need to be used frequently to achieve the best results.
Of course, the wearing of hearing aids is also a step-by-step, continuous adaptation process, which requires long-term wear and use. In the early stage, it took about 1-2 months to adapt to various amplified sounds. The environment gradually transitioned from quiet to complex, and the wearing time was gradually extended from 2 to 3 hours to 8 to 10 hours. As the wearing time is extended and the listening experience is accumulated, the brain hearing sensitivity increases. Users who wear hearing aids every day will be more sensitive to the sound, the brain's response to sound will increase, and the verbal resolving power of the speech center will increase accordingly.
Once you find hearing loss, you should go to the doctor in time. For hearing disorders that cannot be treated and recovered, you should go to a professional institution to perform fitting and use of hearing aids as soon as possible to improve the quality of life.
