Hearing aid selection varies from person to person

　　Uncle Zhang is almost 70 years old this year. Recently, his family has discovered that he has changed from the optimistic and cheerful person he used to be: sometimes he is taciturn, sometimes he has a bad temper, and he deliberately alienates others. Uncle Zhang was brought by his daughter Hospital Do healthy After a physical examination, it was found that Uncle Zhang had severe hearing loss, and the doctor recommended that he wear a hearing aid. It turns out that Uncle Zhang has been suffering from hearing loss in recent years. Recently, his hearing loss has worsened, and he often cannot hear clearly what his family members are saying, which makes him very painful.

　　Situations like Uncle Zhang's are not uncommon. Among the people who choose hearing aids in hearing aid stores, the elderly account for 70% to 80%. Whether a patient should wear a hearing aid and what kind of hearing aid should be worn should be considered based on the nature, degree, medical history, age, living habits, hearing needs, financial affordability and other factors of the deafness.

　　Some patients' deafness is not serious at first. If they are equipped with hearing aids too early, if the volume is adjusted too loud, it will increase the noise and worsen the deafness. Because the function of hearing aids is to amplify sound, not to improve hearing. Therefore, hearing aids for adhesive otitis media have a decrease in sound transmission from the bass to the treble range (poor sound transmission), but those with good cochlear function can significantly improve hearing and have better effects. For chronic otitis media and otosclerosis, surgical treatment should be sought to improve hearing first, and then whether to wear hearing aids can be considered based on the hearing condition.

　　So, what should you pay attention to when choosing hearing aids? Experts suggest that it is best to go to a regular store with professional testing capabilities. When using hearing aids, a comprehensive examination must be carried out by a specialist or professional. According to the different degrees of hearing loss of the individual, the type of hearing aid to be selected must not be worn casually to avoid damaging the remaining hearing. For hearing aids sold in regular specialty stores, the manufacturer is directly responsible. Once a fault occurs, it can be repaired in time, and it can also be maintained, cleaned and dried regularly. There are many types and models of hearing aids, and their prices vary greatly, ranging from a few hundred yuan to tens of thousands of yuan. As far as the hearing aid itself is concerned, the more high-end the hearing aid, the better its noise reduction function and speech clarity. It needs to be reminded that you must not choose inferior hearing aids because you are greedy for cheap or feel that your hearing loss is mild, otherwise it will easily cause "secondary damage" to your hearing.

　　For patients who are already equipped with hearing aids, the careful use and maintenance of the hearing aids cannot be careless. Hearing aids are precision electronic devices and should be protected from moisture, dirt, impacts, water ingress, short circuits, etc. Some patients replace the cheaper non-dedicated batteries by themselves after using them for a period of time. Although the appearance is similar to the dedicated batteries, the thickness is much different, which can easily cause hearing aid failure.
