Why do hearing aids have hearing tests?

Most people should be familiar with hearing aids now, but some people still have the doubt that hearing aids can buy one directly. Why do you have to make it so complicated? Have to check it? There is actually a very simple analogy: glasses Buying one directly is not enough. Why do you want to check your eyesight? Glasses should be familiar to everyone. The glasses we wear must match our vision, otherwise the effect of wearing glasses will not be achieved. Listening is also So, and the hearing is much more complicated.

The human ear can listen to and discern the different natures and different strengths and weaknesses of various sound sources in nature. The sound is transmitted to the inner ear through the outer ear and middle ear, and then reaches the cerebral cortex through the central auditory pathway. The brain analyzes, discerns, and understands the content of various sounds through a comprehensive analysis of sound signals. This is called auditory function. If the system is damaged, it can cause hearing impairment and lead to deafness. Under normal circumstances, the human ear will not be absolutely the same for different frequencies of sound, and the performance will generally be a curve on the audiogram, and the cause of a certain cause of hearing is different for hearing at different frequencies, so it is necessary The amount of compensation that the hearing aid needs to compensate at each frequency point is different. How to determine the amount of compensation at different frequency points needs to be measured beforehand, then the hearing test must be done before the hearing aid is selected.

In addition, with the hearing aid, you can maintain your hearing at the current level or delay the hearing loss, so the hearing may still decline under the influence of certain incentives. At this time, the hearing aid needs to be debugged. Similarly, hearing changes at different frequencies may be different, and the amount of debugging required is different, so there must be a test result.

For infants and toddlers who are pre-lingual, hearing aids and language training are required after wearing a hearing aid. Because of the small sounds that can not be heard or heard for a long time, their hearing function is in the most primitive naive situation, and the hearing is slow. Listening training is to make full use of the residual hearing of the deaf children and awaken their hearing. The research shows that: The situation of mastering language is directly proportional to the effect of listening training. Generally speaking, the more sounds a child hears, the stronger the sound resolution ability, and the faster and better the understanding and mastery of the language.

Here is a phenomenon, including listening and language training, and parents only train language. In fact, this practice is extremely wrong. Listening training and language training are equally important. Listening training should be emphasized, and the age of the child is more important. Small, the more you should strengthen your listening training.

The process of hearing loss is generally silent. Because the human hearing range is very large, the general injury may temporarily affect the communication with others, and there is no detailed hearing test in the regular physical examination, so it is difficult to cause people to be vigilant. The frequency range of the human ear hearing is 20 ~ 20000Hz, above or below this range is not perceived by our ears. When the doctor tests your hearing, it starts from one ear, lets you listen to a series of different frequencies, and records which sounds you can hear and which ones you can’t hear to determine the hearing of each of your ears. The degree of loss, in this way, if there is a problem with hearing, better intervention can be achieved to achieve the best hearing aid for the hearing aid.
