Patent number: 8189833Abstract: A hearing aid comprises two microphones, directional processing means for combining the respective audio signals to form a spatial signal, a beamformer for controlling the directional processing means to provide adaptation of the spatial signal, and means for boosting low frequencies of the spatial signal. A feedback estimator generates a feedback compensation signal, which is combined with the boosted spatial signal. By applying feedback compensation only after directional processing and low frequency boosting, the device avoids interference by the feedback estimator with the function of the beamformer. The invention also provides a method of processing signals in a hearing aid.Type: GrantFiled: April 10, 2008Date of Patent: May 29, 2012Assignee: Widex A/SInventors: Kristian Tjalfe Klinkby, Jorgen Cederberg, Helge Pontoppidan Foeh, Peter Magnus Norgaard, Thilo Volker Thiede

Patent number: 8068629Abstract: A hearing aid (200) with multiple microphones comprises a first microphone (1) for converting sound into a first audio signal, a second microphone (20) for converting sound into a second audio signal, directional processing means for combining the first and said second audio signal according to a mixing ratio to form a spatial signal, estimating means for estimating a first acoustic feedback signal entering the first microphone and a second acoustic feedback signal entering the second microphone, processing means (4) for processing said spatial signal by applying a gain not exceeding a resulting maximum gain limit to form a hearing loss compensation signal, wherein the resulting maximum gain limit is derived from the first and second acoustic feedback signals and the mixing ratio, and an output transducer (3) for converting the hearing loss compensation signal into an acoustic output. The invention further provides a method and a computer program product.Type: GrantFiled: August 5, 2008Date of Patent: November 29, 2011Assignee: Widex A/SInventors: Kristian Tjalfe Klinkby, Peter Magnus Norgaard, Helge Pontoppidan Foeh, Thilo Volker Thiede

Patent number: 6816599Abstract: The present invention relates to an ear level electronic device comprising a housing that is adapted to be worn behind the ear, in the ear, or in the ear canal, and to enclose a music synthesizer for generation of an electrical signal representing music and an output transducer for conversion of the electrical signal into sound. In the device, sound generators are controlled by pseudo-random number generators generating sequences of self-similar numbers whereby music is synthesized that is surprisingly relaxing and comfortable to listen to. Further, a music sequence generated by such a number generator is extremely long so that a person listening to the music does not have a perception of being listening to repeated music sequences.Type: GrantFiled: November 29, 2000Date of Patent: November 9, 2004Assignee: Topholm & Westermann APSInventors: Thilo Volker Thiede, Carl Ludvigsen
