Answer #1

Hearing aid is a device through which speech and environmental sounds are recieved by a microphone, converted to electrical signals, amplified and reconverted to acoustic signals. Hearing aids makes sounds louder but it does not improve a patient's ability to discriminate words or understanding speech.

Deafness or hearing loss impaired the person's ability to hearing. This may lead to social isolation and other problems with person's normal lifestyle.

A hearing aid is the device which restore the hearing ability of a person with hearing disorder. A hearing aid should be fitted according to the patient's needs. That is according to the type of hearing loss, manual dexeterity and preference of patient.
