Abstract: Hearing aid with a microphone, a transmission section (2) for signal processing with a housing (3) containing an output transducer, a battery compartment containing a battery (4), a cover (5) articulated at the housing or a battery lid (5a) articulated at the housing so that it can be pivoted, said cover or lid serving to close off the battery compartment, an electronic control logic (6), as well as a contact arrangement (7) which can be actuated by pressing on the cover (5) in closed position or the battery lid (5a) in closed position and by means of which the control logic can be activated.This contact arrangement can be activated by a spring-loaded movement of the cover (5) or battery lid (5a) beyond the normal closing position.

Abstract: In a remotely controllable, especially remote-control-programmable heating aid with an external control device (1) with a keyboard (2), display device (3) and a data processing device (4) and also a hearing aid (9) controllable by the control device (1), in the control device there is a signal generator (11) actuatable and controllable via the keyboard (2) and the data processing device (4). This generator is releasably connected by a cable (12, 13, 14) to the heating aid so that the control device (1) can be used together with a heating aid to determine the hearing curve or, in general, the audiometric values of the wearer of the hearing aid in real conditions.
