What's the difference between in-ear hearing AIDS and behind-the-ear hearing AIDS? Which is better?

Comparison between small open behind-the-ear hearing AIDS and small in-ear hearing AIDS

Mini open behind-the-ear hearing aid, also known as mini open hearing aid. Different from the traditional behind-the-ear machine, the thin, slim and elastic sound guide tube is more comfortable to wear. The application of open earplugs makes the air in the ear circulate and the internal and external pressure constant, thus unloading the low-frequency energy and reducing the annoying ear blocking effect. Therefore, the matching power of open ears is lower than that of traditional behind-the-ear hearing AIDS, generally below 80dB. Suitable for users with mild and moderate losses. It has been popular in Europe and America for many years, bringing a new trend of wearing hearing AIDS.

The first open hearing aid was born in 2003. At present, the first-line brands in the world have launched their own open hearing AIDS.

The size of the mini CRT is only 37% of that of the traditional behind-the-ear hearing aid, and its weight is only 2g. The external receiver kit is connected to the hearing aid host through an external catheter with special metal wires. The diameter of the outer catheter is only 1.5mm, which is beautiful and compact, and a variety of shell colors can be selected, which makes it easier to get close to human skin color and has better wearing effect. Ear canal receiver technology (CRT) is a kind of ultra-small, very portable behind-the-ear hearing aid (BTE), which is attached behind the ear and connected to the ear through an almost invisible small catheter. The compact receiver placed in the ear canal provides high-quality sound, which can provide a more natural sound feeling and less "ear blocking" effect than traditional hearing AIDS.

CRT, also known as ear canal receiver technology, integrates the microphone and receiver of the traditional behind-the-ear hearing aid into the hearing aid. CRT technology is to separate the receiver from the hearing aid host, put it directly into the ear canal, and connect it with an external catheter with a special metal wire, so that the hearing aid host part can be' slimmed down' successfully.

The advantages of CRT are as follows:

1, naturally improve the gain and sound output, and the power is more powerful, which can meet the needs of severely hearing patients.

2. Smooth output frequency response curve makes the overall loudness bigger, easy to achieve the purpose of compensation, and the sound quality is more beautiful.

3. The frequency compensation range is wider (100- 10000Hz), which can make better use of the frequency response range and make more high-frequency compensation.

4. The distance between the microphone and the receiver is longer, which can effectively eliminate the acoustic feedback.

5, the receiver is closer to the eardrum, and the sound is more natural and realistic.

6, reduce the ear blocking effect, for the ear mold, because the microphone and the receiver are far away, a larger vent hole can be applied; For earplugs, you can choose open or semi-open earplugs.

7. The appearance is smaller, more beautiful and more hidden.

Both types of hearing AIDS have the advantages of small size, beautiful appearance and reduced ear blocking effect. However, the mini open behind the ear machine is miniaturized at the expense of function and power consumption; The mini ear canal receiver behind the earphone line is miniaturized by separating the receiver. Compared with the mini ear canal receiver, the mini ear canal receiver has better functions and power. At the same time, compared with the two models, the mini ear canal receiver behind the earphone is more affordable.
