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

Die Klangqualität bei einem Hörhilfegerät mit einem Richtmikrofonsystem (1A, 1B, 1C) soll verbessert werden. Hierzu werden die Mikrofonsignale (R0, R1, R2) von Mikrofoneinheiten (1A; 1A, 1B; 1A, 1B, 1C) mit Richtwirkungen unterschiedlicher Ordnung analysiert und in Frequenzbänder eingeteilt. Es erfolgt eine Gewichtung der von den Mikrofoneinheiten (1A; 1A, 1B; 1A, 1B, 1C) mit Richtwirkungen unterschiedlicher Ordnung ausgehenden Mikrofonsignale (R0, R1, R2) in den einzelnen Frequenzbändern. Die Gewichtung erfolgt insbesondere in Abhängigkeit des Signalpegels der Mikrofonsignale (R0, R1, R2).

The sound quality of a hearing aid with a directional microphone system (1A, 1B, 1C) is to be improved. For this purpose, the microphone signals (R0, R1, R2) are analyzed by microphone units (1A, 1A, 1B, 1A, 1B, 1C) with directivities of different order and divided into frequency bands. A weighting of the microphone signals (R0, R1, R2) originating from the microphone units (1A; 1A, 1B; 1A, 1B, 1C) with directional effects of different order takes place in the individual frequency bands. The weighting takes place in particular as a function of the signal level of the microphone signals (R0, R1, R2).
