Advantages and disadvantages of box hearing aids

Advantages and disadvantages of box hearing aids

1.The power of the box hearing aid is large

Compared with in-the-ear hearing aids and behind-the-ear hearing aids, box-type hearing aids are the most powerful hearing aids. These hearing aids are large-sized, analog-type hearing aids, and are more suitable for patients and hands with severe sputum. Unskilled elderly people.

2.Box hearing aid acoustic feedback

The earphones of the hearing aid are far away from the microphone receiving the sound, and it is not easy to generate acoustic feedback.

3.Easy to adjust the box hearing aid

Box hearing aid switch/The volume potentiometer knob is large in size, easy to use and easy to adjust.

4.Box hearing aid battery province

The battery used in the box hearing aid is usually5No. of ordinary batteries, long time and cheap.

5.Box hearing aids are low in price

The box type hearing aid itself is low in cost, so the price is low, and the use and maintenance are convenient.

Shortcomings of cassette hearing aids

1.Box hearing aids produce friction with clothing

The box type hearing aid is mainly placed in the user’s pocket or on the clothes. When the person is exercising, the clothes will rub against the hearing aid to generate noise, which will affect the effective listening of the sound.

2.Increase unnecessary low frequency gain

Since the box type hearing aid is placed on the human body, the human body is equivalent to a barrier, and external sound waves are transmitted to the body, and the sound of the low frequency portion can be reflected to the microphone of the hearing aid, thereby increasing the low frequency gain of the hearing aid. For most deaf people, too much low-frequency gain is unhelpful. One is because most of the deaf’s residual hearing, low frequency is better than high frequency, so it is hoped that the hearing aid will have better hearing compensation in the high frequency part. The low frequency part requires relatively little compensation. Moreover, the low-frequency reflection gain of the box-type hearing aid can adversely mask the high-frequency amplification of the hearing aid, thereby reducing the adaptability of the box-type hearing aid. Second, since most of the environmental noise belongs to the low frequency range, the body low frequency reflection gain effect of the box type hearing aid will significantly amplify the environmental noise, and the signal to noise ratio of the box type hearing aid becomes smaller, and the speech intelligibility decreases.

3.Box-type hearing aids are not beautiful for most adult people. They are reluctant to let others find themselves to be deaf. They are reluctant to choose box-type hearing aids because of their self-respect. With the increase of age, the deaf children have increased their self-esteem and wear a box-type hearing aid with wires. Make them clearly feel that they are different from other children. Some children with good recovery have the desire to not hear or listen to hearing aids after entering ordinary primary and secondary schools. This is inseparable from the appearance of the box hearing aids that detract from their self-esteem.

4.Box hearing aids are not convenient to wear

The box type hearing aid must be worn on the clothes, and the volume is too large, which is very inconvenient when the hot clothes are thin or participate in sports.
