Abstract
A hearing-aid system having two hearing aids that automatic detect a “telephoning” hearing situation and automatic deactivating of the hearing aids on being removed from the head. The hearing aids each include a sensor device to detect if a magnetic field exceeds a specific field strength. Data pertaining thereto can be exchanged between the hearing aids via wireless signals. If a magnetic field is detected by only one of the two hearing aids, then it can be inferred therefrom that the “telephoning” hearing situation applies. If, conversely, both hearing aids detect a magnetic field simultaneously, then both hearing aids are will be deactivated automatically.

6. A hearing-aid system, comprising:
-
a first hearing aid and second hearing aid, each hearing aid is wearable on or in an ear of a user, each hearing aid includes; an input transducer that picks up an input signal and converting it into an electric input signal, a signal-processing unit that processes and amplifies the electric input signal and feeds out an electric output signal, an output transducer that converts the electric output signal into an output signal that is perceived by the user as an acoustic signal, a sensor device that detects an external magnetic field that exceeds a specific field strength, a transmitter for transmitting a signal wirelessly between the hearing aids, wherein data relating to the presence of an external magnetic field detected by at least one of the hearing aids is transmitted to other hearing aid, and wherein when the sensor device of one of the hearing aid detects a magnetic field while the sensor device of the other hearing aid does not detect a magnetic field the hearing aid detecting the magnetic field is automatically switched to a telephony hearing situation, and wherein when the sensor device of one of the hearing aid detects a magnetic field while the sensor device of the other hearing aid detects a magnetic field the hearing aids automatically switch off. - View Dependent Claims (7, 8, 9, 10)

11. A method for operating a hearing-aid system, comprising:
-
providing a first and second hearing aid each wearable on or in a ear of a user, hearing aid includes; an input transducer that picks up an input signal and converting it into an electric input signal, a signal-processing unit processes the electric input signal and generates an electric output signal, and an output transducer converts the electric output signal into an output signal perceivable by the user as an acoustic signal, detecting the presence of an external magnetic field that exceeds a specific field strength by at least one of the hearing aids; wirelessly transmitting data relating to the detected presence of the external magnetic field to the other hearing aid; automatically switching to a telephony hearing situation when one of the hearing aid detects a magnetic field while the other hearing aid does not detect a magnetic field; and automatically switching off the hearing devices when each hearing aid detects a magnetic field.
