What kinds of hearing AIDS are there?

First, according to the different output conduction modes, there are bone conduction and air conduction hearing AIDS.

Due to the limited users and effects, bone conduction hearing AIDS are rare. Another kind of hearing aid specially designed for the extremely deaf is called tactile hearing aid, which can convert acoustic energy into vibration energy, transmit information through the user's skin, and help the user indirectly perceive language.

Second, in general, what we call hearing AIDS refers to the traditional air conduction hearing AIDS, which are divided into four categories:

Box, behind-the-ear, glasses, in-ear and ear canal hearing AIDS. Glasses and hearing AIDS are extremely rare.

Three, according to the different lines are divided into analog hearing AIDS and digital hearing AIDS.

The signal processing circuit used in traditional hearing AIDS is analog. Compared with analog hearing AIDS, hearing AIDS with advanced digital signal processing mode are called digital hearing AIDS. As for digitally programmed hearing AIDS, most people think it is a transitional variety between analog and digital.

Fourthly, there are some special hearing AIDS:

For example, frequency-shifting hearing AIDS can automatically convert high-frequency input signals into low-frequency signals, or conversely, patients with unilateral deafness use interactive (CROS) hearing AIDS. In a sense, cochlear implant is also a kind of hearing aid.
