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 affects an individuals ability to understand speech. It is often manifested as a decreased ability to discriminate between sounds. The top journals are peer reviewed scholarly journals. These provide high quality, meticulously reviewed and rapid publication, to cater the insistent need of scientific community. These journals are indexed with all their citations noted. The top open access journals are indexed in MEDLINE, PUBMED, SCOPUS, COPERNICUS, CAS, EBSCO and ISI.
