Largeurs de bandes nécessaires pour une perception non déformée du caractère tonal d'un bruit blanc à diveaux de ce dernier

Abstract

At each level tested, the observers had to find the cut-off frequencies at which the tonal character of a white noise was beginning to change, by using a low-pass filter in one part of the experiments, and a high-pass filter in another part. The filter bandwidth which is necessary to keep unaltered the perception of the tonal character of a white noise decreases with the level of the noise; the curves obtained differ, however, from the threshold curves

Key Words:

• Tonal character of white noise
• Thresholds of white noise
• Psychoacoustics of white noise
