The fitter selects the line and power of the hearing aid according to the type and degree of hearing loss and the actual needs of the patient, so that the electroacoustic characteristics of the selected hearing aid can meet the hearing loss requirement of the patient and achieve better hearing compensation. This is the choice of hearing aid. The key factor. The basis of this link is to have an accurate evaluation of hearing. In order to get a correct diagnosis, we should go to the otolaryngology head and neck surgery in a regular hospital to check the cause, type and extent of hearing loss, and consult a professional audiologist in a formal institution.


The audiologist will choose according to the actual needs of the patient.Hearing aid. For example, for older hearing loss patients, in addition to meeting current hearing needs in hearing aid selection, consideration should be given to the possibility of further decline in hearing with increasing age, so consideration should be given to the power selection of hearing aids. A certain amount of margin. For patients with hearing fluctuations caused by certain lesions, it is more important to leave room for the power of the hearing aid because of the possibility of hearing deterioration. The patient chooses the appearance of the hearing aid, the extended function, etc.: From the appearance, it depends on whether the size of the hearing aid, the shape and color of the outer casing, the degree of concealment when wearing, etc. meet the individual needs. Usually, for children, because the auricle and the external auditory canal are still in the process of development, a back-type hearing aid can be selected. When the whistle is generated due to ear development, the ear mold can be replaced. More subtle types of hearing aids, such as ear canal or deep ear canal hearing aids, can be considered when their ear development is substantially mature. From the perspective of personal operational ability, people who are not very flexible and who have poor eyesight should consider the difficulty of adjusting the hearing aid and adjusting the small buttons, and choose the type of hearing aid that is easier to operate. From the characteristics of the individual ear canal, people with too narrow ear canal are generally not suitable for the choice of in-ear hearing aids. If you need a larger vent and a more comfortable fit, you can choose a behind-the-ear hearing aid and add a vent to the ear mold.

Step by step, correct use of hearing aids


The use of hearing aids has a certain adaptation time, that is, after the sound is processed by the hearing aid, the original sound will have a certain change, and the patient needs a certain time to adapt to the new sound. For the hearing loss of the first choice hearing aid, this is More obvious. As for the length of adaptation time, this is often related to a variety of factors, such as age, physical condition, degree of hearing loss and time.

When the hearing aids are selected, don’t go to noisy places, such as supermarkets or airports, in the first few weeks. In addition, the time to wear a hearing aid should be slowly increased. In the first few days, the hearing aid should not be worn for more than one to three hours. When you feel nervous or tired, you should take the hearing aid off, rest for a few hours, gradually extend the wearing time, and finally make the hearing aid a friend. During the adaptation period, it is very important to let yourself adjust to the sound of the surrounding environment step by step.

3, use the hearing aid battery correctly. Hearing aids must use a dedicated battery. If the battery is dead, it should be replaced in time. If the battery is low, it will affect the acoustics of the hearing aid. When the hearing aid is not used for a long time, the battery should be taken out to avoid damage to the hearing aid caused by battery leakage.

4Keep the hearing aid clean. When the hearing aid still has no sound or the sound is significantly reduced after replacing the new battery, it should be considered whether the sound hole of the hearing aid is blocked by the ear. You can use the hooks or small brushes in the hearing aid maintenance kit to remove the sputum, but avoid getting too deep or going to the otology clinic. In particular, in-the-ear hearing aids, which are too deep to damage the hearing aid receiver.

According to different classification criteria, the types of hearing aids are also divided into many. I don’t know what you think about the above classification. The role of hearing aids for hearing impaired people, I believe we do not have to say that everyone knows. Therefore, when purchasing, be careful, don’t be greedy and cheap.
