Abstract

Verfahren zum Betrieb eines Hörhilfegerätes sowie Hörhilfegerät mit einem Mikrofonsystem, bei dem unterschiedliche Richtcharakteristiken einstellbar sindMethod for operating a hearing aid and hearing aid with a microphone system, in which different directional characteristics are adjustable

Bei einem Hörhilfegerät mit einem Mikrofonsystem (1, 2; 21, 22) sollen beim Umschalten zwischen unterschiedlichen Richtcharakteristiken entstehende Artefakte vermieden werden. Hierzu sieht die Erfindung vor, dass von Mikrofoneinheiten ((1; 1, 2), (21; 21, 22)) mit Richtcharakteristiken unterschiedlicher Ordnung ausgehende Mikrofonsignale (R0, R1; R0', R1') in ihren Signalpegeln angeglichen werden. Das Umschalten bzw. Überblenden erfolgt dann stets zwischen Mikrofonsignalen (R0, R1; R0', R1') mit gleichem Signalpegel, so dass durch das Umschalten bzw. Überblenden keine Pegelsprünge entstehen.

Figure imgaf001
In a hearing aid device with a microphone system (1, 2, 21, 22) artefacts arising when switching between different directional characteristics should be avoided. For this purpose, the invention provides that microphone signals (R0, R1, R0 ', R1') output from microphone units ((1; 1, 2), (21; 21, 22)) with directional characteristics of different order are adjusted in their signal levels. The switching or cross-fading then always occurs between microphone signals (R0, R1, R0 ', R1') with the same signal level, so that no level jumps occur due to the switching or cross-fading.
