Hearing aids are the medical devices which are designed to amplify the sound for an individual. It is basically an electro acoustic 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 affects an individual’s ability to understand speech. It is often manifested as a decreased ability to discriminate between sounds. Scholarly journal is a peer-reviewed journal in which scholarship relating to a particular academic discipline is published. Scholarly journals serve as forums for the introduction and presentation for scrutiny of new research, and the critique of existing research.
