1 Definition

Air-conduction hearing aids are personal amplifying devices (consisting of microphones, amplifiers, battery power sources, sound processors, and receivers) that pick up, amplify, and process incoming sounds and direct them to the ear canal. Hearing aid styles include: body, behind-the-ear, in-the-ear, in-the-canal, completely-in-the-canal, and open-canal fittings to meet patients’ personal desires and amplification needs. Circuitry includes: analog, which simply amplifies incoming sounds, and digital, which converts analog sounds to digital formats for all signal processing and then changes the resulting stimuli back to analog form as it is directed to the ear. Most hearing aids now use digital circuitry and their advanced features can benefit persons having losses ranging from slight to profound. They are usually used for SNHLs and can have important HRQOL benefits for users and their families.
