Abstract
- Bereitstellen einer Anzahl von Basisfunktionen (BFi,11A,...), die jeweils eine grundlegende Eigenschaft eines spektralen Verlaufs von Teilübertragungsfunktionen (HRTF') aufweisen,
- Erzeugen der angenäherten Teilübertragungsfunktion (HRTF'',17,17') durch Kombination der mit Wichtungsfaktoren (A,B,13A,...) gewichteten Basisfunktionen (BFi, 11A,...), indem für jede Basisfunktion (BFi,11A,...) jeweils der Wichtungsfaktor (A,B,13A,...) derart bestimmt wird, dass ein Betrieb des elektroakustischen Geräts (1,3,3A,21) unter Berücksichtigung der mit den Wichtungsfaktoren (A,B,13A,...) und Basisfunktionen (BFi, 11A,...) gebildeten angenäherten Teilübertragungsfunktion (HRTF'',17,17') an ein akustisches Umfeld (43) angepasst ist,
- Abspeichern der angenäherten Teilübertragungsfunktion (HRTF'',17,17') im elektroakustischen Gerät (1,3,3A,21) zur Benutzung während des Betriebs.
