Abstract

Die Erfindung betrifft ein Hörhilfegerät (11) mit
- einem Eingangswandler (12) zur Aufnahme eines Eingangssignals und Wandlung in ein elektrisches Eingangssignal (ES) ;
- einer Signalverarbeitungseinheit (14, 15, 16) zur Verarbeitung und frequenzabhängigen Verstärkung (V, V1, ..., V8) des elektrischen Eingangssignals und Erzeugung eines elektrischen Ausgangssignals (AS);
- einem Ausgangswandler (18) zur Wandlung des elektrischen Ausgangssignals in ein akustisches Ausgangssignal;
- eine Laut-Detektor-Einrichtung (19) zum Erkennen von Lauten in einem in das Hörhilfegerät eingehenden Sprachsignal;
- Mittel (20) zur kurzzeitigen Anhebung (V6') der Verstärkung (V6) über eine normale Verstärkung (VN) hinaus für einen Frequenzbereich (K6), in dem ein erkannter Laut Signalanteile aufweist;
- Mittel zur Einstellung der normalen Verstärkung eines elektrischen Eingangssignals in Abhängigkeit von der Signalfrequenz (f);
wobei
- die Verstärkung wenigstens in einem bestimmten Frequenzbereich (K1, ..., K8) auf eine dauerhaft mögliche, maximale Verstärkung (VMax) begrenzt ist;
- die Verstärkung wenigstens für die Dauer des erkannten Lautes und höchstens für eine Dauer, die unter einer Einschwingzeit eines Feedback-Pfeifens liegt, die normale Verstärkung oder die maximale Verstärkung übersteigt.
