Abstract (en)
[origin: US4723293A] A hearing aid apparatus has a housing containing components such as a microphone, an amplifier and an earphone,and to which a terminal having contacts for connection to a signal line is applied. The terminal also has contacts for derivation of signals from the microphone so that a conventionally operating hearing aid is achieved which also contains an audio output in addition to an audio input. The hearing aid apparatus is thus particularly suitable for use as a talk/listen set in aural training systems.
