Child hearing aidChild hearing aidMatching principle

Child hearing aidThe fitting is a systematic project and a long-term project. Because the degree of development, mental state, vision, intelligence, and responsiveness of the auditory system are quite different from those of adults, the hearing aid fitting of children must rely on the cooperation of the hearing aid fittings and parents to achieve the desired results. So what are the principles to follow in fitting child hearing aids?

1Accurate audiology and medical diagnosis: audiology and medical diagnosis must be clear (including the integrity of the middle ear, inner ear and auditory nerve, cochlear structure; auditory neuropathy, large vestibular aqueduct syndrome and other metabolic and hereditary disease syndromes) Wait.

2, obtain accurate and full frequency bands (at least should include0.5 k,1k,2kAnd4kHzPoint) The level of hearing loss (recommended not to use the results of multi-frequency steady-state directly), that is, to obtain an accurate hearing curve of binaural accuracy that can be used for hearing aid fitting.

3Medical professional fitting: In addition to the hearing aid and audiology professional related issues, the hearing aid fitting also involves the baby’s comprehensive medical assessment. Such as the diagnosis of developmental delay, tongue ligament, large vestibular aqueduct syndrome, auditory neuropathy and cerebral palsy and intelligence, cytomegalovirus infection, auditory development of children and mental development.

4Both sides of the hearing loss must be equipped with a hearing aid on both sides.

5Avoid non-intervention and insufficient intervention: When the subjective and objective examination of audiology does not lead to the reaction, it is often considered that there is no residual hearing. In fact, most of them have some residual hearing. Therefore, early (less than1Years) should not give up the fitting of hearing aids. If the hearing aid fitting is invalid, the electronic cochlear implant can be considered.

6Avoid excessive intervention. That is to say, if the hearing aid is not equipped with a hearing aid, we already know that there are problems with hearing developmental delay and test errors (the test must be repeated twice).(About7%), especially for the diagnosis of patients with mild to moderate hearing loss. Over-diagnosis in early (less than six months of age) interventions will occur, and over-diagnosis will inevitably lead to excessive interventions, and appropriate interventions must be made.

7Infants and young children should choose high-performance hearing aids as much as possible. High-performance hearing aids have the advantages of increased sound fidelity, wide range, and fast processing and high-performance.

8Hearing aids must be tested early, while adhering to the family-based auditory and speech rehabilitation training.

9,Child hearing aidAnd proper maintenance and regular follow-up of the ear mold.
