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.

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.

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:

  1. Compactness.
  2. Simplicity and ease.
  3. Continued use without battery replacement.
  4. When the battery ends, the device illuminates the charge indicator.
  5. Ensuring a clean and legible sound.
  6. There is a protective system against the ingress of sulfur into the device.
  7. 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:

  1. 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.

  4. 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.
