In-ear hearing aid: a device, how much is
How to construct an intracanal hearing aid?
Violation of the functionality of hearing – alarm signal, saying, that you need to see a doctor — audiologist. Steady hearing loss can go for various reasons, and often the treatment does not produce results, but it is not considered a sentence.
When a hearing problem is not subject to medical treatment, resorted to using a hearing aid. Today there are many different models of devices, but in this article, we will analyze the in-ear hearing aid.
Intracanal hearing devices
Hearing AIDS – a unique invention of engineering, which allows to compensate for hearing loss. To apply the device when the hearing threshold exceeded 35dB.
Nowadays in-ear hearing AIDS are the most convenient devices used for hearing AIDS. They are set at the beginning of the channel of the external auditory canal, is firmly adhered to its wall and the corresponding, form.
Devices (ITC) made from a cast of the ear, taking into account all individual characteristics of the patient. This kind of model has plus the fact that it is not noticeable to others, as is the deeper into the passage than vnutrishniy model.

The device allows you to communicate by phone because it closes the auricle. Earlier devices of this type compensate for a small degree of hearing loss, at the moment they are upgraded, and they can handle even the fourth degree of hearing loss.
Devices developed on the basis of high-precision digital technologies, their performance sound reinforcement and noise reduction is much less pronounced than when using other models. On the external panel, it has a volume control.
Many believe that in-ear hearing AIDS deep dive is more practical than in-ear ITC. But this is not true. This model is inferior to them the large size. It is also a cheaper device and is used to compensate for more significant hearing losses.
To choose the in-ear device for the correction of hearing should be exclusively physician-audiologist after a detailed diagnosis.
Description and principle of operation of the device
In-ear hearing aid is considered to be the most compact in relation to other species. Camera as tight to the walls of the passage, providing the highest performance. It is made and adjusted on the basis of the recommendations of the doctor and the individual patient.
In-ear hearing AIDS are digital. The principle of operation is based on removing the digital code of sound vibrations. Further, this code is converted into a sound signal that detects auditory organs.
Hearing aid receiver it is desirable to remove at night and also when the person is alone. The fact that the constant presence in the ear foreign object leads to a violation of the secretory processes, the emergence of itching.
Is the device an average of 5 years. It has batteries that need to be replaced every 15 days. As the operation of the device is damaged due to clogging then gray, so it should be cleaned, and then carry on adjustment to the servicing center.
How much for in-ear hearing aid depends on the quality of the sound and its purity. On the market there are many options of domestic and foreign manufacturers. The cost of domestic in-ear devices starts from 25, 000 and can reach up to 100 000 rubles.
Machines from abroad for the excellent quality of material components, therefore cost far more. Also have imported the device, whose price starts from 50 000 rubles and reaches up to 200,000 rubles.
The pros and cons of intracanal hearing devices
This kind of model have a number of advantages in comparison with other types of devices that increase the sound:
- Simplicity and ease.
- Continued use without battery replacement.
- When the battery ends, the device illuminates the charge indicator.
- Ensuring a clean and legible sound.
- There is a protective system against the ingress of sulfur into the device.
- After a while, there is a habituation to the device, the mechanism ceases to be a nuisance.
Now we will describe the shortcomings of the hearing aid device:
- The inconvenience of the device is that people with neurological diseases simply can not use the device. His hands were shaking and fiddling with a hearing aid amplifier is not easy. The device is also not recommended to people with poor eyesight and a weak sensitivity of the upper limbs.
- As the microphone and amplifier are close by, in noisy places, the sound is converted is not always correct. You receive a whistle, distracting.
- The device is contraindicated in children under 12 years and teenagers with inflammatory diseases of the ear. The apparatus at the time of treatment replaced, on ear model.
- When a person has chronic otitis media, then the device can not be set. The liquid accumulating in the hearing aid body negatively affects the device operation.
Summarizing, we notice that a hearing doctor, audiologist gives General guidance and direction of the hearing aid. And the device model selection is provided to the patient. Here you can find out which hearing AIDS are considered the best.
If the choice is to consider the capacity. It should be sufficient not only to compensate for existing loss of hearing, but also to have a reserve. Perhaps in the future it will be useful, and hearing AIDS from the category of expensive goods.
