ABSTRACT:
A portable communication apparatus (10) for communication between a first person of normal hearing ability and a second person whose hearing is impaired is disclosed. The communication apparatus includes a first housing (12) enclosing a microphone and an amplifier, the first housing (12) being adaptable for being carried in a coat pocket or the like of the first person. The communication apparatus further includes a second housing (22) constructed and arranged to fit over the ear of the second person. The second housing (22) includes means for receiving electrical signals from the amplifier and converting the electrical signals into sound. An electrical connector (20) electrically connects the receiving means in the second housing (22) with the amplifier in the first housing (12) whereby the voice of the first person is amplified and transmitted to the receiving means in the second housing (22), thereby enabling the second person to hear the first person.
