Abstract

Die Sprachverständlichkeit eines Audiosignal bei unveränderter Lautstärke wird verbessert, in dem das gesamte Audiosignal um einen konstanten Faktor angehoben und die Amplitude dieses angehobenen Signales durch einen Hochpass abgesenkt wird. Die Eckfrequenz fc des Hochpasses wird dabei so geregelt, dass die Ausgangsamplitude des Audiosignals am Ende der Verarbeitungsstrecke gleich oder proportional der Eingangsamplitude des Audiosignals ist.
