Intrachannel hearing aid: description, types, features and reviews
The main organs that give a person the joy of perception of the world around him are hearing, sight and speech. The loss of the normal functioning of one of these organs reduces the quality of life. Especially often due to age-related changes, people lose their hearing. But in modern society, with a high level of development of medicine and the technological process, this problem is easily solved. In case of hearing impairments, an in-channel hearing aid comes to the rescue.
General characteristics of hearing aids
The hearing aid is a special device, by means of which the function of hearing is replenished. The work of this device consists in reproducing sounds by recognizing and amplifying, clearing from third-party noise interference, increasing their purity and clarity.
The difference between the hearing aid and the sound amplifier is that the first is multifunctional and more efficient, the second one because of the limitation by the sole purpose adversely affects the hearing, subsequently contributing to its complete loss. The quality of sounds does not change when using a sound amplifier, it just becomes louder. Therefore, an intracannular hearing aid is preferable. Comments differ depending on the type of device.
The hearing instruments of domestic and foreign origin available in the Russian market are assembled from several elements. This is the case of the device, inside which there is a special microphone and sound amplifier, a telephone. At more advanced devices there is also an integrated microprocessor. Outside the body there is a fastening part.
The in-channel hearing aid functions as follows. The microphone catches from the environment sounds, which turn into electrical. Then these sounds are sent to the amplifier in series. In the amplifier, the degree of their sound is transformed, after which they turn into a telephone to turn sounds into vibrations.
If the device is equipped with a microprocessor, then after the phone the sounds are processed in it, where their quality improves, clearing of foreign interference, is given clarity to the reproduction. The microprocessor can have separate settings for each person individually.
Types of hearing aids and classification
According to their characteristics, the way of reproduction, fastening, etc., hearing aids are divided into different types. The choice to make is very difficult. It will be more correct to seek help from a specialist or a doctor, choose a hearing aid according to your own individual characteristics. Looking ahead, we note that the hearing aid is an intracannel. The invisible mechanism makes it especially in demand among patients.
By the degree and form of the transformation and reproduction of sounds, they are divided into several types.
Analog hearing aids
One of the most inexpensive types of hearing aids. Used a little in connection with its simplicity and not the highest quality and convenience. Preference is given to him only because of the low price. These devices differ in that they do not improve the quality of sound reproduction, just strengthening it. All sounds amplify, those that were available to a person, and no. As a consequence, it is difficult for a patient to understand the essence of what he has heard. They make the patient uncomfortable because of poor quality of the sound.
Digital hearing instruments
These are advanced mechanisms that reproduce high-quality sounds. Hearing aids are very popular. In-channel devices are equipped with built-in microprocessors, which convert sound by several criteria, giving out in the final result that quality that is more convenient for a person. The owner of the hearing aid practically does not notice the difference between the previous one hundred percent hearing and the one that is compensated by the device.
According to the ability to determine sound, the apparatuses are divided into several types.
Air conduction hearing aids
The most popular devices in high demand. This is due to their multifunctionality. They allow you to improve hearing in almost any violation. Thanks to such devices, a person hears not only the sounds that are nearby, but also those that are reproduced by means of telecommunications.
Apparatus for bone conduction of sound
These are used to restore the conductivity function of sounds. Not the most popular devices due to their functional limitations. According to the attachment method, the apparatuses are also subdivided.
BTE hearing aids
The most common. They consist of two parts. The body of the hearing aid itself, which is placed on the outer side of the auricle, and a thin channel of polymer material inserted into the ear, through which sounds are heard. They come in different sizes, modifications. They are recognized as very convenient. Inside the case there are batteries that are easily replaced. The device has a pre-warning function that the battery will be exhausted soon. Compact and convenient.
Intrachannel hearing aid
They are very similar to the intrauterine, but differ in the method of placement and size. Such a mechanism is placed in the cavity of the auditory canal, which increases the sound quality.
It is used in almost all types of hearing impairment, including extreme hearing loss. Such a device is mounted inside the auditory canal, thanks to its work, the sound is reproduced more cleanly, with greater clarity. It is very compact, almost invisible to the eyes of others. Very little weight and no additional inconvenience. This is practically the most expensive kind of hearing aids.
Intra-channel hearing aids: reviews and prices
The built-in hearing aid processor is manufactured and configured on the basis of the doctor's recommendations and the individual characteristics of the customer. They are single in manufacture and are not mass produced. Each patient orders the device for himself. According to the reviews of doctors and patients, it is superb and with prolonged wearing is almost imperceptible.
Will serve such an in-channel hearing aid of the order of 2 or 3 years, depending on the intensity of use. Because of the location inside the ear, it is damaged due to clogging during sweating, segregation of sulfur, etc. It is equipped with replaceable batteries. The batteries must be replaced every 10-14 days.
All hearing aids are recommended to be taken off at night, cleaned in a timely manner and provided with careful operation. In the event of a malfunction for repair of equipment in the organizations that produce this product, there are service centers. Parts for repairing the hearing aid can also be purchased from the manufacturer.
How can I choose an in-channel hearing aid? The price of the device depends also on the quality of sound reproduction. The purer it is, the more expensive the apparatus is. The starting price of domestic in-channel devices is from 30 000 rubles. Can reach 100,000 rubles for more advanced models.
In the market of hearing aids are presented inter-channel devices of domestic and foreign manufacturers. They differ in the quality of the material and components, of which an in-channel auditory device is made. The devices of foreign manufacturers are much more expensive.
The market also features an imported intracanal hearing aid. The price of such a device starts from 50,000 rubles and comes to 200,000 rubles. The more expensive models have the option of replacing parts in part and extending the service life, which is initially longer.
