Hearing aids are a kind of electronic products, and can not replace the human ear, wearing a hearing aid can immediately return to normal hearing concept is not scientific. Hearing aids have evolved from analog machines to digital machines, and even the current high-end all-digital machines, which can meet people's listening requirements in more and more complex environments. The mission of hearing aids is to enable people with hearing loss to enjoy the same communication opportunities as normal people with high-quality hearing aids. Your expectations of hearing aids are related to your listening needs, and the final result depends on your choice of model. There is no doubt that hearing aids are useful for people who are deaf, but how useful they are for hearing rehabilitation depends on the following factors: (1) Be realistic in your expectations of hearing aids and understand the performance characteristics of hearing aids. As a medical device, a hearing aid cannot solve all the problems of a patient. Only when the patient fully understands the characteristics of hearing aids can he or she give up unrealistic ideas. (2) Correctly selecting hearing aids. Hearing aid selection is an important part of hearing rehabilitation. Different patients have different degrees of deafness. Hearing aid fitting is a means to help patients effectively utilize their residual hearing. Therefore, the patient must go to a professional organization to make the correct selection, so that the hearing aid can play a maximum role.
