Abstract: The application relates to a hearing device comprising a beamformer of the generalized sidelobe canceler (GSC) type. The application further relates to a method of operating a hearing device. The disclosure addresses a problem which occurs when using a GSC structure in a hearing device application. The problem arises due to a non-ideal target-cancelling beamformer. As a consequence, a target signal impinging from the look direction can—unintentionally—be attenuated by as much as 30 dB. To resolve this problem, it is proposed to monitor the difference between the output signals from the all-pass beamformer and the target-cancelling beamformer to control a time-varying regularization parameter in the GSC update. This has the advantage of providing a computationally simple solution to the non-ideality of the GSC beamformer. The invention may e.g. be used in hearing aids, headsets, ear phones, active ear protection systems, or combinations thereof.

Abstract: The present invention regards a hearing system configured to be worn by a user comprising an environment sound input unit, an output transducer, and electric circuitry. The environment sound input unit is configured to receive sound from the environment of the environment sound input unit and to generate sound signals representing sound of the environment. The output transducer is configured to stimulate hearing of a user. The electric circuitry comprises a spatial filterbank. The spatial filterbank is configured to use the sound signals to generate spatial sound signals dividing a total space of the environment sound in subspaces.

Abstract: An improved scheme for identifying and removing musical noise in an audio processing device can be achieved in an audio processing device that includes an analysis path with a perceptive model of the human auditory system and provides an audibility measure. The device may also identify an artifact introduced into the processed signal by the processing algorithm and provide an artifact identification measure, and control a gain applied to a signal of the forward path by the processing algorithm based on the perceptive model. An advantage is to dynamically optimize noise reduction with a view to audibility of artifacts and is applicable to hearing aids, headsets, ear phones, active ear protection systems, hands-free telephone systems, mobile telephones, teleconferencing systems, public address systems, karaoke systems, and classroom amplification systems.
