Abstract

Bei Akustiksystemen insbesondere bei Hörgeräten tritt immer wieder Rückkopplungspfeifen auf. Um dies zu vermeiden, wird daher ein Grenzverstärkungsfrequenzgang (g) der Verstärkungseinrichtung, welcher die Grenze für Rückkopplungspfeifen darstellt, aufgenommen. Anhand der aufgenommenen Kurve wird ein Sollverstärkungsfrequenzgang (se) mit mehreren Stützpunkten, bei dem jeder Stützpunkt zu dem Grenzverstärkungsfrequenzgang (g) in mindestens zwei verschiedenen Richtungen einen jeweils vorgegebenen Minimalabstand besitzt, erstellt. Dadurch kann Rückkopplungspfeifen auch bei Verschieben von Resonanzfrequenzen größtenteils verhindert werden.
