Hearing aids

Reference information: www.entific.com.hk


Hearing aids are often the first consideration for patients with hearing disabilities. These aids can be similarly considered like glasses for visual problems. They do not require surgery and the advanced technology is relatively inexpensive. Patients can used them when they want and remove them as necessary.

There are many different types of Hearing aids available. They vary in size, quality, performance and therefore, price. Hearing aids should always be tailored to the different needs and hearing disability of the user. Hearing aids are however, not without their own problems. Patients may well find them uncomfortable or conspicuous to wear. This perhaps more so if the benefit offered is insufficient to meet the patients’ expectation and needs.

Conventional Hearing aids require a sound leak proof occlusion of the ear canal by the ear mold in order to work well. Patients may find the fitting ear mold a little uncomfortable to use. Also, slight movement could alter its position easily and this can create feedback whistling sound, when the amplified sound leaks out of the ear canal, and re-enters the microphone of the same hearing device. This is similar to the whining feedback during karaoke sessions when the sound is picked up by the same microphone in a reverberating circuit.

When properly prescribed and fitted, conventional Hearing aids are a good option to rehabilitate most hearing problems.
