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 individualâs ability to understand speech. It is often manifested as a decreased ability to discriminate between sounds. Journal Article is sometimes called a Scientific Article, a Peer-Reviewed Article, or a Scholarly Research Article. Together, journal articles in a particular field are often referred to as The Literature. Journal articles are most often Primary Research Articles. However, they can also be Review Articles. These types of articles have different aims and requirements. Sometimes, an article describes a new tool or method. Because articles in scientific journals are specific, meticulously cited and peer-reviewed, journal databases are the best place to look for information on previous research on your species. Without a background in the field, journal articles may be hard to understand - however, you do not need to understand an entire article to be able to get valuable information from it.
