Convention Paper

Discrimination of Formant Frequency in Pink Noise

Authors: Rogala, Tomira

AES Convention 140 · Paper 9583 · May 2016

Abstract

The paper reports an experiment conducted to determine discrimination thresholds for timbre in tonmeister students and non-musicians. The variations of timbre were obtained through introducing a 1/3-octave wide formant into the spectrum of noise and shifting the formant’s center frequency. Discrimination thresholds were measured using a 3AFC procedure. The results have shown that the threshold values determined for tonmeister students were considerably lower than those obtained for non-musicians. In both groups of listeners a learning effect was observed: the thresholds decreased in successive measurement series completed by a listener. It also was found that the formant frequency discrimination thresholds depended on the formant frequency and were much higher at 125 Hz than at 315 Hz and higher frequencies.
