The main organs that give a person the joy of perceiving the world around us are hearing, sight and speech. 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. For hearing loss, an in-ear hearing aid comes to the rescue.
General features of hearing aids
A hearing aid is a special device with which the function of hearing is replenished. The operation of this device is to reproduce sounds by recognizing and amplifying, clearing third-party noise interference, increasing their purity and clarity.
The difference between a hearing aid and a sound amplifier inthe fact that the first is multifunctional and more effective, while the second, due to its limited use by a single purpose, adversely affects hearing, subsequently contributing to its complete loss. The sound quality does not change when using the sound amplifier, it just gets louder. Therefore, an in-ear hearing aid is still preferable. Reviews vary depending on the type of device.
Hearing devices of domestic and foreign origin available on the Russian market are assembled from several elements. This is the body of the device, inside which there is a special microphone and sound amplifier, telephone. More advanced devices also have a built-in microprocessor. Outside, there is a fastening part on the case.
The in-ear hearing aid functions as follows. The microphone picks up sounds from the environment, which turn into electrical ones. These sounds are then sent sequentially to the amplifier. The degree of their sound is converted in the amplifier, after which they are transferred to the phone to turn the sounds into vibrations.
If the device is equipped with a microprocessor, then after the phone the sounds are processed in it, where their quality is improved, purification from extraneous interference, clarity is given to reproduction. The microprocessor can have separate settings for each person individually.
Types of hearing aids and classification
According to their characteristics, playback method, attachment, etc., hearing aids are divided intodifferent kinds. The choice is very difficult to make. It would 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 in-ear hearing aid is popular. The invisible mechanism makes it especially popular among patients.
According to the degree and form of transformation and reproduction of sounds, they are divided into several types.
Analogue hearing aids
One of the most inexpensive types of hearing aids. It is used little due to 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, only amplifying it. All sounds are amplified, those that were accessible to a person, and not. As a result, it is difficult for the patient to understand the essence of what he heard. Causing inconvenience to the patient due to poor sound quality.
Digital hearing aids
These are advanced mechanisms that reproduce high quality sounds. Digital hearing aids are in high demand. In-ear devices are equipped with built-in microprocessors that convert sound according to several criteria, giving the final result the quality that is more convenient for a person. The wearer of the hearing aid hardly notices the difference between the previous 100% hearing and the one that is compensated by the hearing aid.
According tothe ability to determine the sound devices are divided into several types.
Air conduction hearing aids
The most popular devices in high demand. This is due to their versatility. 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.
Bone conduction sound machines
These are used to restore the function of the conduction of sounds. Not the most popular devices due to their functional limitations. According to the method of attachment, the devices are also divided.
Behind the ear hearing aids
The most common. Consist of two components. The body of the hearing device itself, which is placed on the outer side of the auricle, and a thin channel made of polymer material, inserted into the ear, through which sounds are heard. They come in various sizes and modifications. They are found to be very comfortable. There are batteries inside the case that can be easily replaced. The device has a pre-warning function that the battery will soon be discharged. Compact and comfortable.
Intracanal hearing aid
They are very similar to in-the-ears, but differ in placement and size. Such a mechanism is placed in the cavity of the auditory canal, which increases the sound quality.
Used in almost everyall types of hearing loss, including severe hearing loss. Such an apparatus is attached inside the auditory canal, thanks to its work, the sound is reproduced cleaner, with greater clarity. It is very compact, almost invisible to the eyes of others. It weighs very little and does not cause additional inconvenience. This is almost the most expensive type of hearing aid.
Intracanal hearing aids: reviews and prices
The processor built into the hearing aid is manufactured and adjusted based on the recommendations of the doctor and the individual characteristics of the customer. They are single in production and are not mass-produced. Each patient orders the device for himself. According to the reviews of doctors and patients, it is super comfortable and almost imperceptible when worn for a long time.
This in-ear hearing aid will last about 2 or 3 years, depending on the intensity of use. Due to its location inside the ear, it is damaged by blockage due to perspiration, wax production, etc. It is equipped with replaceable batteries. Batteries should be replaced every 10-14 days.
All hearing aids are recommended to be removed at night, cleaned in a timely manner and ensure gentle operation. In the event of a malfunction, there are service centers at the organizations that produce these products to repair equipment. Hearing aid repair parts are also available from the manufacturer.
How to choose an in-ear hearing aid? The price of the device also depends onsound reproduction quality. The cleaner it is, the more expensive the device itself. The initial price of domestic intracanal devices is from 30,000 rubles. It can reach 100,000 rubles for more advanced models.
Intracanal devices of domestic and foreign manufacturers are presented on the hearing aid market. They differ in the quality of the material and components from which the in-ear hearing device is made. Devices from foreign manufacturers are much more expensive.
The market also features imported in-ear hearing aids. The price of such a device starts from 50,000 rubles and reaches 200,000 rubles. More expensive models have the ability to replace part of the parts and extend the service life, which is initially longer.
