Hearing aids are devices that amplify any sound and make it audible to hearing impaired persons. These devices deliver the amplified sound directly to the person’s ear. There are many types of hearing aids that vary in size starting from the larger ones to extremely smaller ones which remain almost invisible. With the advancement of technology, hearing aids are not only diminishing in size, but are also evolving with more and more features that give specific and even customized facilities. The design of different types of hearing aids is also improving gradually starting from sleek ones to extremely trendy ones, hence, opening up many options for the patients to choose according to their specific preferences. Some devices are extremely hassle-free and are very comfortable to wear.

Studies have shown that a majority of the people worldwide who are using hearing aid devices, are extremely happy with the experience and they are not deprived of leading a normal life.

Different types of hearing aids serve different functions depending on the type or degree of the hearing impairment that one is suffering from. These devices are used mainly to treat one of the major types of hearing loss, namely sensorineural hearing loss. Also, these hearing aids are prescribed based on the degree of hearing loss, which range from mild, moderate, severe and profound. The devices are fitted in the patient’s ear after an examination of the type and degree of hearing impairment, done by the audiologists. The outcome of a hearing aid device can be represented by three main dimensions, namely, the usage of the device, aided speech recognition and the benefits or advantages of the device.
