Abstract:
A method operates a hearing device. A first input signal is generated by a first input transducer of the hearing device from an ambient sound signal. An external input transducer outside of the hearing device generates an external input signal from the ambient sound signal. A relative transfer function from the external input transducer to the hearing device with respect to a target signal source is ascertained based on the first input signal and/or external input signal. The external input signal is filtered by the relative transfer function, thereby generating an estimated target signal. Noise suppression takes place in the hearing device based on the estimated target signal.

Claim (Index 16):
A hearing device system, comprising:\n a hearing device having at least one first input transducer for generating a first input signal; an external input transducer for generating an external input signal; and a processor unit programmed to operating said hearing device to perform the following steps of:\n generating, via said at least first input transducer of said hearing device, the first input signal from an ambient sound signal; \n generating, via said external input transducer, the external input signal outside said hearing device from the ambient sound signal; \n ascertaining a relative transfer function from said external input transducer to said hearing device with respect to a target signal source based on the first input signal and/or the external input signal; \n filtering the external input signal using the relative transfer function resulting in an estimated target signal being generated; and \n performing noise suppression in said hearing device based on the estimated target signal.
