AUDIOPHONE (from Latin audire-to hear and Greek phone-sound), a hearing aid that serves as an auxiliary means of hearing for the deaf and is based on the amplification of sound by a microphone; the operating principle of the audiophone is a form of electrical energy used in the telephone. In addition to the audiophone, there are also a whole series of hearing aids by various authors, such as: aurophone, acouphone, acousticophone, electrophone, francophone, otion.
