Features Of The Cassette Hearing Aid

Box hearing aids are also called body-worn or pocket hearing aids. The shape is a rectangular box the size of a small radio, the microphone, amplifier and battery of the hearing aid are assembled in it, and a long wire is connected to the earphone and earplugs or special ear molds. It is usually placed in a clothes pocket or a special pouch.

This type of hearing aid has a relatively large volume and is suitable for the elderly and people with inconvenient finger movements. The microphone (microphone) of the hearing aid is far away from the receiver (headphone), which is not easy to produce acoustic feedback, so its maximum output limit is small, the power can be made large, and multiple manual adjustment knobs can be placed. It is cheap and easy to maintain. It uses AA or AA batteries, and can also use rechargeable batteries. Body-worn hearing aids can also be made into binaural hearing aids, because such hearing aids are large in size and poor in concealment. Hearing aids use ordinary transistor components, which have a high background noise. In addition, the friction between the hearing aid itself and the wire and clothes makes the sound easily distorted and the sound quality is reduced. At the same time, the earphone wire is easily damaged, which is unsafe for children to wear.
