- 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.
- Audiophonology — An interdisciplinary branch of medicine and behavioral sciences dealing with the integrated study of hearing, vocal emission mechanisms, and verbal communication disorders; the science of audition and phonatory correlation. The field combines knowledge from otolaryngology, neurology, acoustics, and logopedics.
