Hearing Aids Scientific Journals
Hearing
aids are the medical devices which are designed to amplify the sound for an individual. It is basically an electroacoustic device. The primary aim of a hearing aid is to make speech more detectable by rectifying an impaired hearing as detected by audiometry. There are different types of hearing aid instruments, which usually differ in their size, power and circuitry. Though hearing
aids are found to be very useful in case of deaf individuals but hearing
aids as such are incapable of correcting a
hearing loss completely. They simply act as an aid that make sounds
perception more accessible for deaf individuals. As the cell loss in the primary auditory cortex region of the
brain increases the degree of
hearing loss also increases. This region of the
brain is concerned with the processing of sound on receiving the regular stimulations. Damage to the hair
cells of the
inner ear also results in
hearing loss which affect an individualÂ’s ability to understand speech. It is often manifested as a decreased ability to discriminate between sounds. One of the challenges facing hearing care providers when recommending hearing
aids is the choice of device technology level. Major manufacturers market families of hearing
aids that are described as spanning the range from basic technology to premium technology. Premium technology hearing
aids include acoustical processing capabilities (features) that are not found in basic technology instruments. These premium features are intended to yield improved hearing in daily life compared to basic-feature devices.
