- Audiophone — A small acoustic apparatus or device used in the past to amplify sounds, designed to assist individuals with partial hearing impairments; a mechanical precursor to the modern hearing aid. In early applied physics, it could also describe an instrument capturing sound vibrations via bone conduction.
- Audiologist — A specialist in audiology; a healthcare professional who focuses on the prevention, identification, non-invasive diagnosis, and clinical management of hearing and balance disorders in children and adults. The audiologist performs specialized tests, interprets charts, and fits digital hearing aids.

She evaluates patients with hearing loss, interprets audiometric charts, calibrates hearing aids, and coordinates acoustic rehabilitation programs.
- Audiology — A branch of medicine and biology that deals with the study of hearing, the structure and function of the auditory apparatus, and the diagnosis, prevention, and treatment of hearing impairments or loss; the science of hearing. This discipline merges clinical and technical knowledge to evaluate acoustic sensitivity.
