Child hearing aidHow to match[Skill finishing]
How to choose the right child hearing aid? Professional fitting is essential! In the daily reception of hearing aid stores, we found that many parents have a phenomenon or misunderstanding for buying hearing aids for their children: parents only think that expensive models or good models are bought by others! Hearing is here to sum up a few tricks to teach you how to choose the right child hearing aid.
The child’s hearing test report is just a few things: acoustic impedance, auditory brainstem potentialABRMulti-frequency steady stateASSR(sacrum)CTImpact check (displaying the middle, inner ear and inner auditory condition) and so on. Hospitals generally only do these objective tests. In general, these results must be converted into units of pure tone hearing: listening level analysis, they can only predict residual hearing, and there is an error in the actual hearing loss (pure listening behavior). For children who are still unable to complete pure tone audiometry, parents should eliminate the need for visual enhancement and other behavioral audiometry and multi-frequency steady state to choose to buy hearing aids! Before choosing a hearing aid, try to cooperate with the fitter to conduct a subjective behavior test and combine the behavior test results.ASSRBrain stemABRReport to fully understand the child’s hearing loss and hearing quality.
Children’s hearing loss is generally more serious, and the hearing is difficult to measure very accurately, chooseChild hearing aidShould reserve enough gain. If the child’s low frequency hearing loss has a frequency defect, or the overall low frequency hearing loss is reached100dBAnd the low frequency of the behavioral listening and listening control is also greater than90Above, please consider choosing675Battery digital machine. The high frequency is greater than110Children, if the low frequency is also very poor, then parents need to be prepared for the electronic cochlea, before the artificial cochlear implant for children, if the age is acceptable (small age is generally less than18Children of the month) It is best to use a super power hearing aid for at least half a year. Wearing a hearing aid with such a large hearing loss may not achieve good results, but if the child can understand the simple words after wearing the hearing aid, the risk of poor effect after implantation of the cochlear implant is greatly reduced. When choosing a hearing aid for a very severe child, you should fully consider the low-frequency compensation effect and the gain of the hearing aid. You must hear it before you hear it!
Parents who are interested may notice that children who have good effects in hearing the brand’s hearing aids also have children who are not very effective. In fact, the primary determining factor for children’s wearing hearing aids is the child’s hearing and what causes it. Hearing loss, the hearing aid just amplifies the sound so that the child can hear the original speech (before the hearing aid is not heard), which is what every brand can do, otherwise it can not be called a hearing aid, that is to say From the single aspect of the effect, as long as the power of the hearing aid is appropriate, there is almost no difference between the hearing aids of each brand.
However, there are some differences between different brands in terms of design details, noise control concept, product stability, water resistance, children’s ear hooks, etc. These differences can hardly affect the effect, but will be comfortable and post-service. Relevant to the degree of complexity, such as a product stability and poor waterproof performance, increased maintenance rate in the later period, will delay the child’s language training time.
In summary, parents should not be able to chase the wind when they choose a hearing aid brand because they see that a child is wearing a certain hearing aid. This is extremely irrational.
The ear-back hearing aid is also an in-ear hearing aid. The ear-back type has a large appearance and is easy to be found on the ear. However, because the resonance sound tube is long, good sound quality can be obtained, and the power is large, and the child can change the ear mold. Time does not affect the child’s use. The custom machine is small and beautiful, but the relative power is smaller. If it is a small child, it will not be used for too long. Because the child’s ear canal needs to change the outer casing, the hearing aid can not be used during the replacement of the outer casing, so the parents and the fitting The teacher has some difficulties in choosing. Generally speaking, if the child is too young, it is less than5Years old, the choice of custom machine to change the casing too often, should not be chosen, and if the family is not too concerned about the appearance of the case is recommended to choose the ear back machine, use the ear mold. If you want to use a custom machine, your child’s age should be a little bigger, and the ear canal changes are not as fast as you can consider.
Child hearing aidAt the same time, some details of the fitting should be considered at the same time. The details often determine the effect of the fitting. Ear model is the most important point in many details. For example, children with low frequency can be said to be lucky. After choosing the right product, you must choose the appropriate open ear mold to fully protect your child’s low frequency hearing and expand the child as much as possible. The low-frequency listening field allows the child to hear more real sounds in order to achieve both comfort and safety. Parents in smaller cities, if they don’t have these technical support, should try to urge the fitter to make hard ear molds for the low-frequency children and open the air holes. When a child with high frequency hearing loss chooses an ear mold, there is still a detail to consider. It is best to choose a reinforced ear mold sound tube to prevent the attenuation of the high frequency compensation effect. Only by fully considering the details will the perfect compensation effect of the hearing aid be used to help the child get out of the first step in life.
If the child’s hearing aid is selected without the hearing aid effect evaluation, the child’s hearing compensation situation: whether it is heard clearly, how much can be heard clearly, whether it is comfortable to listen, whether it will damage the residual hearing, etc., so that the hearing aid is sold. Don’t buy it! Otherwise, parents will fall into: the hearing aid effect is not ideal – change the machine – the language training effect is not ideal – cochlea – the cost of money, time and energy is difficult to count, the real fallacy is the child’s recovery of gold period.
An excellent fitter with high technology and good character is far more important than the hearing aid itself! Professional hearing aids in addition to basic audiology knowledge, but also have hundreds of children’s audiometry and fitting experience. Whether communication with the child is in place, whether the patience is enough, whether the explanation with the parents is enough, and whether it is scientific enough. The best hearing aids, in addition to the quality of the hearing aids, depend more on the professional selection and adjustment of the hearing aid fittings.Child hearing aidThe fitting requirements are higher and more professional!
