Abstract

Experimental approaches to the determination of psychological parameters for complex sounds are discussed and relevant studies are summarized. The results of a series of experiments which were conducted treating the problems of parameters for complex sounds are included in this report. The studies involved language of auditory experience, scaling of auditory stimulus sets on equal-interval scales, paired-comparisons scaling, scaling by direct magnitude estimations, observer generated scales, multidimensional scaling of groups of sounds, and changes in auditory perception under constant stimulation. The results of the various studies indicated that the most promising approach for the study of parameters of complex sounds was that the most promising approach for the study of parameters of complex sounds was the multidimensional scaling model. In a pure tone study this scaling model isolated the expected dimensions, pitch and loudness. In the scaling of complex sounds, for several stimulus sets evaluated, between three and six dimensions appeared to emerge.
