Audiology
Audiology is the branch of science and healthcare that studies hearing, balance, and related disorders, encompassing diagnosis, management, and prevention of auditory and vestibular system conditions.
Overview
Audiology is a multidisciplinary field that combines elements of neuroscience, acoustics, and clinical medicine to understand and treat disorders affecting hearing and balance. The discipline emerged in the mid-20th century, particularly following World War II, when many veterans returned with hearing damage.
Core Components
Diagnostic Assessment
Audiologists employ various testing methods to evaluate hearing function:
- Pure tone audiometry
- Speech audiometry
- Tympanometry
- Otoacoustic emissions testing
- Auditory brainstem response testing
Treatment and Management
Treatment approaches include:
- Hearing aid selection and fitting
- Cochlear implants
- Aural rehabilitation
- Tinnitus management
- Vestibular rehabilitation
Specialized Areas
Pediatric Audiology
Focuses on hearing assessment and intervention in children, including:
- Newborn hearing screening
- Early intervention programs
- Educational audiology
- Language development support
