Abstract

Die Erfindung betrifft ein Verfahren zur richtungsabhängigen Rauschunterdrückung für ein Hörsystem (2), welches eine Hörvorrichtung (1) umfasst, wobei anhand wenigstens eines ersten Eingangswandlers (21) des Hörsystems (2) und eines zweiten Eingangswandlers (22) des Hörsystems (2) aus einem Schall der Umgebung ein Störsignal (36) und ein Zielsignal (40) erzeugt werden, wobei das Störsignal (36) und/oder das Zielsignal (40) auf eine in einer Ziel-Richtung (38) angeordnete Nutzsignalquelle bezogen sind, wobei das Zielsignal (40) mit einer Ziel-Richtcharakteristik erzeugt wird, welche über einen der Ziel-Richtung (38) entgegengesetzten Halbraum (66) hinweg homogen oder im Wesentlichen homogen verläuft, wobei für wenigstens eine erste Mehrzahl an Frequenzbändern jeweils ein eine akustische Kenngröße (42, 46) des Zielsignals (40) mit einer entsprechenden akustischen Kenngröße (42, 44) des Störsignals (36) verglichen wird, und anhand des besagten Vergleichs ein vorläufiger Gewichtungsfaktor (51) ermittelt wird, dessen Wertebereich (80) wenigstens drei Werte (80a, 80b, 80) aufweist, wobei für das Frequenzband anhand des vorläufigen Gewichtungsfaktors (51) jeweils ein Gewichtungsfaktor (54) für das jeweilige Frequenzband gebildet wird, undwobei ein zu verarbeitendes Eingangssignal (56) des Hörsystems (2) frequenzbandweise anhand des jeweiligen Gewichtungsfaktors (54) gewichtet wird, und anhand des so gewichteten zu verarbeitenden Eingangssignals (56) ein Ausgangssignal (58) erzeugt wird.The invention relates to a method for direction-dependent noise suppression for a hearing system (2), which comprises a hearing device (1), wherein at least a first input transducer (21) of the hearing system (2) and a second input transducer (22) of the hearing system (2) a noise from the environment, an interference signal (36) and a target signal (40) are generated, the interference signal (36) and/or the target signal (40) being related to a useful signal source arranged in a target direction (38), the target signal (40) is generated with a target directional characteristic, which runs homogeneously or essentially homogeneously over a half-space (66) opposite the target direction (38), wherein for at least a first plurality of frequency bands an acoustic parameter (42, 46) of the target signal (40) is compared with a corresponding acoustic parameter (42, 44) of the interfering signal (36), and based on said comparison a preliminary weighting factor (51) is determined, the value range (80) of which has at least three values (80a, 80b, 80), a weighting factor (54) being formed for the respective frequency band for the frequency band on the basis of the provisional weighting factor (51), and a to processed input signal (56) of the hearing system (2) is weighted by frequency band based on the respective weighting factor (54), and based on the thus weighted input signal (56) to be processed an output signal (58) is generated.
