Abstract

Die Erfindung betrifft ein Hörhilfegerät (HA; HA1, HA2) mit einem Richtmikrofonsystem, umfassend wenigstens
- ein erstes Mikrofon (F; F1, F2), von dem ein erstes Mikrofonsignal (SF; SF1, SF2) ausgeht,
- ein zweites Mikrofon (B; B1, B2), von dem ein zweites Mikrofonsignal (SB; SB1, SB2) ausgeht,
- eine Verzögerungseinheit (T), wobei zum Erzeugen einer Richtwirkung das zweite Mikrofonsignal oder ein daraus hervorgehendes viertes Mikrofonsignal (SB3, SB4) mittels der Verzögerungseinheit um eine interne Zeitverzögerung (Ti; Ti1, Ti2) verzögert und mit dem ersten Mikrofonsignal oder einem daraus hervorgehenden dritten Mikrofonsignal (SF3, SF4) zum Erzeugen eines Richtmikrofonsignals (SD) verknüpft wird,
- eine Kreuzkorrelationsanalyseeinheit (K1, K2), in die das erste oder das dritte Mikrofonsignal und das zweite oder das vierte Mikrofonsignal eingehen, zur Bestimmung eines Werts einer Kreuzkorrelation der beiden Mikrofonsignale;
- eine Steuereinheit (C1, C2) zum Einstellen der Zeitverzögerung in Abhängigkeit von dem Wert der Kreuzkorrelation der beiden Mikrofonsignale;
- einen Klassifikator (K) zum Bestimmen einer Hörsituation, in der sich das Hörhilfegerät gerade befindet,
wobei
- die Einstellung der Zeitverzögerung in Abhängigkeit von der Hörsituation erfolgt.
