First of all, let's understand the hearing aid:
Hearing aid is a small amplifier, the original inaudible sound to be enlarged, and then the use of hearing impaired people's residual hearing, so that the sound can be sent to the auditory center of the brain, and feel the sound. It is mainly composed of five parts: microphone, amplifier, headphone, power supply and volume control. Hearing aids are divided into air-conducting hearing aids and bone-conducting hearing aids according to the way of conduction; classified by the way of use as box-type, eyeglasses-type, hairpin-type, back-of-the-ear-type, in-the-ear-type, ear-canal-type, and deep ear canal-type hearing aids.
We probably understand a hearing aid that we look at what it will do:
Choosing the right hearing aid on the one hand can protect their residual hearing, to avoid excessive sound to the ear caused by further
hearing loss; on the other hand, can also improve the ability to differentiate speech, the ability of the individual's response to the situation will be better and better. Having a hearing loss and not using hearing aid intervention all the time will, on the contrary, aggravate hearing difficulties and accelerate the process of auditory degradation. To be precise, wearing a hearing aid that has been accurately fitted and is of good quality and suitable for the individual's hearing will not cause the hearing to become heavier and heavier, nor aggravate the degree of deafness, but will instead help to slow down the process of deafness. Especially children are still in the learning stage, found that hearing loss, if you want to choose the right product for them as soon as possible, scientific and reasonable fitters will not cause harm to the body.
Hearing aids are a "match" rather than a "purchase" from the store. Like eyeglasses, hearing aids are a scientific and precise process. Before fitting, the doctor will first take a medical history, then conduct a comprehensive hearing test and evaluation, and draw an audiogram. Then the doctor will put the selected hearing aid in the hearing aid tester, through more than a dozen tests, to see whether its performance is up to standard. Finally, the doctor will try on the hearing aid for a period of time according to each person's unique ear structure. If there is any subjective discomfort, the dispenser will repeatedly adjust the hearing aid's various Palm control devices to achieve the best results. No two hearing impaired exactly the same, so be sure to according to their own unique hearing loss, to choose a truly suitable for their own hearing aids.
