Audiology is a branch of healthcare that deals with the study, diagnosis, and treatment of hearing and balance disorders. It involves the assessment and management of hearing and balance disorders in people of all ages, from newborns to the elderly. Audiology professionals, known as audiologists, use a variety of tests and techniques to identify and evaluate hearing and balance problems, and develop customized treatment plans to help patients manage their condition. They may also work with individuals with hearing loss to provide hearing aids, cochlear implants, and other assistive devices to improve their hearing ability.
