The difference between children’s hearing aid and adult’s hearing aid

Due to the influence of age, there is a great difference in the cooperation between adults and children in the hearing test, so there will be some differences in the items that need to be tested.

For adults, because they can correctly understand the instructions of the matching personnel, they can basically meet the needs of the matching of hearing aids by performing pure tone audiometry. By analyzing the relationship between the air conduction curve and bone conduction curve, we can determine the nature of deafness and the selection of hearing aids; by analyzing the relationship between comfort threshold and discomfort threshold curve, we can determine the dynamic range of hearing and the way to limit the output of hearing aids; by analyzing the changes of air conduction curve at various frequency points, we can determine the degree of hearing loss and the most important part of hearing aids High output (power of hearing aid). It should be pointed out that for the elderly patients, speech audiometry should be included as a necessary item of hearing test because the hearing ability of the auditory pathway and the auditory center will also be affected.

Children, especially the young deaf children, because their cognitive ability can not meet the requirements of accurately understanding the meaning of various subjective listening tests, so the accuracy of their subjective listening tests will be affected to some extent, and the results of listening tests can not accurately reflect their true listening, this must be remembered. Because of this, children’s hearing test should increase objective methods as much as possible, such as the aforementioned auditory brainstem melon, acoustic immittance, multi frequency steady-state response, etc., or children’s hearing aids should refer to their subjective and objective listening test results as much as possible to make the matching more accurate.

Use of various functions of hearing aids

Adults are very clear about the purpose of hearing aid fitting, so they can take the initiative to adapt to hearing aids and overcome the discomfort brought by some hearing aids subjectively, while children often passively accept hearing aids. Their adaptation to hearing aids is semi mandatory. When they are unwilling to wear them, they should take some distracting methods and let them rely on the passage of time Only when people feel the benefits of hearing aids can they really be willing to use them Adults can take the initiative to adjust and develop the functions of hearing aids, so they should be given more autonomy in setting volume, program switching, battery replacement, etc. while for children, they should be given more autonomy in programming, so as to prevent their misoperation from causing the function of hearing aids not to play normally. Generally speaking, for the deaf children who wear hearing aids for the first time, there is no manual volume adjustment function; the program can reduce the energy as much as possible, the compensation of high, middle and low frequency should be balanced; the battery compartment should be locked, etc. After they or their parents are familiar with hearing aids and understand their children’s hearing compensation, gradually add some self-adjusting functions.

Matching and evaluation

The subjective feeling of the wearer should be fully considered in the hearing aid matching of adults. The experience of the wearer is more important in the hearing aid matching of children Adults can well express the quality of the sound information they hear. Therefore, for them, the evaluation of the effect of hearing aids should be mainly based on the functional evaluation, and attention should be paid to the evaluation in different sound environments. For children, because they have no listening experience, they cannot correctly describe the meaning of the sound they hear. Therefore, the evaluation methods of the effect of hearing aids are mainly quantitative evaluation.

Use of various functions of hearing aids

Because most adults have mature experience of language listening and have good language foundation, they generally do not need speech rehabilitation training. Their rehabilitation instruction after wearing hearing aids mainly includes: tell them how to use and maintain hearing aids, such as how to switch, how to install and remove batteries, how to adjust volume, how to switch programs, how to remove ear molds, how to dry hearing aids, etc., how to adapt to hearing aids as soon as possible, when they first wear hearing aids, the wearing time is from short to long, and the sound of hearing aids Learn to use auxiliary devices of hearing aids, such as magnetoelectric induction device, wireless frequency modulation system, etc. After children’s hearing aids are worn, the rehabilitation guidance should mainly focus on the development of hearing training and speech training plan, so that they can complete the process of hearing awareness, hearing discrimination, hearing recognition and hearing understanding as soon as possible, and learn, master and use language in this process.
