Abstract

The adjustment equipment on the outside of the ear protective cover forms part of a circuit located in the cover, and which works in conjunction with the circuit in the hearing appts. It is coupled via a long cable (11) to bridge over a current switch (5) and a volume control unit (R1,C1). Adjustment for volume control in the cover works in conjunction with components (R2,R3,C2) with similar values and shape as the components in the normal volume control unit. The cover has a microphone, a hearing coil and an electronic circuit for transmission of output signals from the microphone, suitably transformed, to the coil.
