Fully digital circuitry allows implementation of many additional features not possible with analog circuitry, can be used in all styles of hearing aids and is the most flexible; for example, digital hearing aids can be programmed to amplify certain frequencies more than others, and can provide better sound quality than analog hearing aids.
A bone-anchored hearing aid (BAHA) [2] is a type of hearing aid based on bone conduction.It is primarily suited for people who have conductive hearing losses, unilateral hearing loss, single-sided deafness and people with mixed hearing losses who cannot otherwise wear 'in the ear' or 'behind the ear' hearing aids.

Within the medical model deafness is conceptualized from a "personal tragedy" stance, indicating that it should be avoided, eradicated, or normalized by all possible means. [ 16 ]
They dispense, manage, and rehabilitate hearing aids and assess candidacy for and map hearing implants, such as cochlear implants, middle ear implants and bone conduction implants.

An audio induction loop, also known as a hearing loop, provides assistance to hearing aid users. The system has one or more loops in the area in which a hearing aid user would be present. Such an induction loop receiver is classically a very small iron-cored inductor . The system commonly uses an analog power amplifier matched to the low ...
