Abstract

Die vorliegende Erfindung betrifft ein Verfahren zur Erzeugung eines Audiosignals (02) für ein synthetisches Geräusch eines Kraftfahrzeuges. Im Weiteren betrifft die Erfindung das genannte Audiosignal (02) für das synthetische Geräusch eines Kraftfahrzeuges. In einem Schritt des erfindungsgemäßen Verfahrens wird ein Signal (01) bereitgestellt, welches ein Rauschen darstellt. Weiterhin wird eine Grundfrequenz festgelegt, welche eine Betriebsdrehzahl des Kraftfahrzeuges repräsentiert. In einem weiteren Schritt werden mehrere Filter auf das Signal (01) des Rauschens angewendet. Die Filter weisen jeweils eine Mittenfrequenz auf, welche über einen Ordnungsfaktor mit der festgelegten Grundfrequenz verknüpft ist. Zumindest mehrere der Ordnungsfaktoren sind ganzzahlig, sodass diese Filter Oberwellen der Grundfrequenz filtern. Die Ordnungsfaktoren und Amplitudenverläufe der Filter sind entsprechend einer Klangcharakteristik des zu synthetisierenden Geräusches des Kraftfahrzeuges ausgewählt. Das durch die Filter bewertete Signal (02) des Rauschens stellt das Audiosignal (02) für das synthetische Geräusch des Kraftfahrzeuges in Abhängigkeit von der Betriebsdrehzahl des Kraftfahrzeuges dar.
