Abstract
A method operates a hearing system that has a first input transducer, a second input transducer and a signal processing device. An activity of a lateral useful signal source in an environment of the hearing system is ascertained by a first input signal being generated via an acoustic signal that impinges on the first input transducer, and a second input signal being generated via the acoustic signal that impinges on the second input transducer. A filtered input signal is generated via a directional notch filter based on the first and second input signals. A measure for attenuation that the directional notch filter causes is ascertained based on the filtered input signal and on the first and/or second input signals. The measure is compared with a reference, and from this comparison, the presence or absence of activity of the lateral useful signal source in the surroundings is inferred.
