Difference between children’s hearing aids and adult hearing aids

Hearing test Because of the age, there is a big difference in the degree of cooperation between adults and children in the hearing test, so there are some differences in the items that need to be tested.

For adults, because they can correctly understand the instructions of the fitters, they only need to perform pure tone audiometry to basically meet the needs of hearing aid fitting. By analyzing the relationship between the air conduction and the bone conduction curve, the nature of the deafness can be determined, and the choice of the hearing aid can be determined. By analyzing the relationship between the comfort threshold and the discomfort threshold curve, the dynamic range of the hearing can be determined, and the acoustic output limitation of the hearing aid can be determined. By analyzing the change of the air conduction curve at each frequency point, the degree of hearing loss can be judged and the maximum output of the hearing aid (power of the hearing aid) can be determined. It should be pointed out that for elderly patients, because of the hearing ability of the auditory conduction pathway and the auditory center, speech hearing should be classified as a mandatory hearing examination item.

In children, especially younger children, because cognitive ability does not meet the requirements of accurately understanding the meaning of various main observations, the accuracy of their main observations will be affected, and the results of the audiometry cannot accurately reflect them. The true hearing, this must be remembered. It is precisely because of this, children’s hearing test should try to increase the objective methods, such as the aforementioned auditory brain stem, acoustic impedance, multi-frequency steady-state response, etc., or pediatric hearing aid fitting should try to refer to their The subject and the guest observe the results to make the fitting more accurate.

Use of various functions of hearing aids

The purpose of adult hearing aid fitting is very clear, so they can actively adapt to hearing aids, subjectively to overcome the discomfort of some hearing aids, and children are often passively receiving hearing aids, their adaptation to hearing aids is semi-mandatory When they are not willing to wear them, they should adopt some distracting methods, and let them feel the benefits of hearing aids by time to be really willing to use them. Adults can actively adjust and develop the functions of the hearing aids. Therefore, they should give them more autonomy in the setting of volume, program switching, battery replacement, etc. for fitting. The settings are given during programming to prevent them from malfunctioning and the function of the hearing aid does not function properly. Generally speaking, for the younger children who wear the hearing aid for the first time, there is no manual adjustment function of the volume; the program should be reduced as much as possible, the compensation of the high and low frequency should be balanced; the battery compartment should be locked. Wait until they or their parents are familiar with the hearing aids; and after understanding their own hearing compensation, gradually add some features that can be adjusted.

Fitting and evaluation

For adult hearing aid fitting, the subjective feeling of the wearer should be fully considered. The hearing aid fitting of children is more dependent on the experience of the fitter. Adults can very well express the quality of the sound information they hear. Therefore, for them, the evaluation of the hearing aid effect should be based on functional evaluation. Note that it must be evaluated in different sound environments, but for children, because they are not listening. Experience, can not correctly describe the meaning of the sound heard, therefore, the evaluation method of hearing aid effect is mostly based on quantitative evaluation.

Use of various functions of hearing aids

Since most adults have a mature experience of listening to the language, they have a good language foundation and generally do not need training in speech rehabilitation. Their rehabilitation guides after wearing hearing aids mainly include: telling them how to use and maintain hearing aids, such as how to switch, how to install and remove the battery, how to adjust the volume, how to switch programs, how to pick up the ear mold, how to dry the hearing aid, etc. How to adapt to hearing aids as soon as possible, when wearing hearing aids, the time of wearing from short to long, the volume of hearing aids from small one to large, the environment from quiet to complex, etc.; learn to use hearing aids, such as magnetic induction devices, wireless frequency modulation System, etc. Rehabilitation guidance for pediatric hearing aids should be based on the development of auditory training and speech training programs, so that they can complete the process of auditory perception, auditory resolution, auditory recognition and auditory understanding as soon as possible, and learn, master and use the language in the process.
