Audiology is the branch of science that studies hearing, balance and related disorders. Audiologists treat those with hearing loss and proactively prevent related hearing damage. These health professionals use various hearing tests to determine whether someone can hear within a normal range, and if not, which portions of hearing (high, middle, or low frequencies) are affected and to what degree. If an audiologist determines that a hearing loss or physical abnormality exists he or she will provide recommendations on what options (e.g. hearing aid, cochlear implants, surgery, appropriate medical referrals) may help.

In addition to testing hearing, audiologists can also work with a wide range of clientele in rehabilitation (cochlear implants and/or hearing aids), children’s hearing issues and assessment of the hearing system.
