ABSTRACT:
For reducing the power consumption of a hearing aid system, an internal or external hearing aid signal source with a signal line for the transmission of a signal to a hearing aid amplifier and a control device for the connection and disconnection of the hearing aid signal source is provided in the hearing aid. A monitoring logic monitors the signal line and supplies a switch signal to the control device, so that the hearing aid signal source can be connected and disconnected on the basis of the switch signal. Each signal source can thus be individually connected and disconnected without employing additional connections from the hearing aid system to the signal source.
