Subjects were required to distinguish among two‐component auditory stimuli of the formcosω1t+cos(ω2t+φ)[cf., J. H. Craig and L. A. Jeffress, “Effect of Phase on the Quality of a Two‐Component Tone,” J. Acoust. Soc. Amer.34, 1752–1760 (1962)]. The frequency ratio ω1:ω2was 2:3, and the only difference among stimuli presented in a given session was the phase φ. Stimuli were presented monaurally at low frequency (range 100 Hz–1 kHz) and high intensity (range 60–90 dB SPL). Stimuli were generated and the experiment was controlled by a Honeywell DDP‐516 computer. Subjects made dissimilarity judgments using the method of triadic comparisons, and they also made paired‐comparison judgments of subjective attributes, such as apparent pitch and timbre. The relationships between these subjective attributes and phase of the stimulus change systematically as stimulus frequency or intensity changes. Dissimilarity matrices obtained from the triadic comparisons can be related to pitch and timbre of the stimulus.
