The timbre difference between lowpass-filtered harmonic complex tones of equal loudness and pitch were measured by two different psychoacoustic methods. High correlation was found between the measured timbre differences and the calculated differences in critical-band loudness. Moreover the timbre differences, measured in Bark, can be described either by the differences in sharpness or in LP cut-off frequencies.

Zusammenfassung

In psychoakustischen Versuchen wurden die Klangfarbenunterschiede zwischen tiefpaßgefilterten harmonischen Klängen gleicher Lautheit und gleicher Tonhöhe mit zwei unterschiedlichen Meßmethoden untersucht. Die beobachteten Klangfarbenunterschiede lassen sich gut mit den berechneten Unterschieden der Frequenzgruppenlautheiten der Klänge erklären. Eine wesentlich einfachere weil eindimensionale Beschreibung der Klangfarbenunterschiede ist jedoch durch die Unterschiede in der Schärfe oder in den Grenzfrequenzen, umgerechnet in Bark, möglich.

Sommaire

On a examiné, dans des expériences de psychoacoustique avec deux méthodes de mesure différentes, les différences de timbre entre sons harmoniques filtrés en passe-bas à sonie et tonie égales. Les différences observées pour le timbre s'expliquent convenablement par les différences calculées pour les sonies des bandes critiques. Cependant une description unidimensionnelle, et donc plus simple, reste possible, en utilisant les différences d'acuité subjective des sons, ou les différences dans les fréquences limite, traduites en Bark.
