Advantages and disadvantages of in-ear hearing aids

advantage:

1. Concealability is better than behind-the-ear and box-type hearing aids;

2. The sounding position of the hearing aid is closer to the tympanic membrane. The sound receives less influence on the resonance of the external auditory canal. In theory, it will be more natural and clearer (the actual situation should be analyzed according to the production process and the condition of the ear canal).

Disadvantages:

1, more than the ear type, not suitable for children (the reason is the same as above);

2, the microphone, the receiver is close to each other, easy to produce howling, the production process requirements of the custom machine is relatively high;

3, small size, not easy to operate;

4. The internal movement is easily damaged by the influence of sputum, etc., and the waterproof performance is worse than that of the behind-the-ear hearing aid;

5. For users with lighter hearing loss, it is easy to produce a blocking effect.
