Deafness and hearing aids

The human ear has two major functions as an auditory organ, one is the auditory function; the other is the positional balance function.

Among them, hearing is a reaction to the behavior of sound. From physical stimulation to receiving sound to psychological perception, and even behavioral reaction is a long and complicated neurobiological process. The complex and precise degree of auditory organs makes the most complex machinery in the world today. Electronic equipment is far behind.

There are many artificial hearing devices on the market, mainly hearing aids, artificial hearing bones, artificial electronic cochleas, vibrating acoustic bridges,BAHAEtc., is a rehabilitation product that assists in improving hearing.

Hearing aid

We have seen that many deaf patients who use hearing aids have received a lot of help, from silent to vocal, but still can’t be like normal people, there are many people who use hearing aids are not satisfied, and even complain about these devices.

Hearing aid

The principle of the hearing aid is to amplify the sounds transmitted to the human ear. These amplified sounds pass through the hearing aid placed in the external auditory canal, pass through the middle ear, stimulate the cochlear hair cells located in the inner ear, increase the rate of nerve discharge, and produce auditory perception, which requires the hearing aid to amplify. The sound must match the state of the cochlear hair cells, which is the “hearing aid fitting”.

Hearing aid fitting involves two aspects of work:

First, to understand the patient’s medical history, and then to understand the severity of the patient’s hearing loss and the mechanism of injury; pure tone audiometry, speech audiometry, etc.;

The second is the selection, verification and evaluation of hearing aids. The most important thing is to set the fine parameters. The parameters of the hearing aids directly affect the user’s recognition of the sound and the satisfaction of the auditory scene. Most hearing aids work best in a small or quiet environment.

Currently with artificial intelligenceAIWith the development of technology, more and more hearing aid manufacturers have begun to introduce intelligent hearing aids. The intelligent fitting is more precise, more accurate, less time-consuming and better user experience.

Hearing aids must rely on the patient’s residual hearing to produce auditory perception. The hearing aid is different from the ear. The hearing scene used is very small and cannot be compared with the wide application of the ear. Therefore, the structure of the human ear is exquisite, and the protection of hearing is fundamental. Listening regularly. Check, when there is hearing damage, seek help in time to prevent micro-duration.
