To study the perceptual structure of musical timbre and the effects of musical training, timbral dissimilarities of synthesized instrument sounds were rated by professional musicians, amateur musicians, and nonmusicians. The data were analyzed with an extended version of the multidimensional scaling algorithm CLASCAL (Winsberg & De Soete, 1993), which(More)
The aim of the psychoacoustic study presented here was to characterize listeners' preferences for a set of sounds produced by different models and brands of indoor air-conditiong units. In addition, some synthetic sounds were created on the basis of interpolation among recorded sound samples and were integrated into the set. The approach consisted first in(More)
Timbre spaces represent the organization of perceptual distances, as measured with dissimilarity ratings, among tones equated for pitch, loudness, and perceived duration. A number of potential acoustic correlates of timbre-space dimensions have been proposed in the psychoacoustic literature, including attack time, spectral centroid, spectral flux, and(More)
The dependency of the timbre of musical sounds on their fundamental frequency (F0) was examined in three experiments. In experiment I subjects compared the timbres of stimuli produced by a set of 12 musical instruments with equal F0, duration, and loudness. There were three sessions, each at a different F0. In experiment II the same stimuli were rearranged(More)

In this article we propose an algorithm for Principal Components Analysis when the variables are histogram type. This algorithm also works if the data table has variables of interval type and histogram type mixed. If all the variables are interval type it produces the same output as the one produced by the algorithm of the Centers Method 1 The algorithm In(More)
Can tension in nontonal music be expressed without dynamic or rhythmic cues? Perceptual theories of tonal harmony predict that psychoacoustic roughness plays an important role in the perception of this tension. We chose a set of orchestrated chords from a nontonal piece and investigated listeners' judgments of musical tension and roughness. Paired(More)
One approach to improving sound quality is to create a preference map on the basis of several acoustic parameters relevant to auditory perception. The map is derived from several stages of subjective testing, acollstic analysis, and auditory modeling. The multidimensional scaling technique CLASCAL reveals common perceptual jimensions shared by sets of(More)
We would liketodedicate this article to the memory of our colleague Suzanne Winsberg Summary This paper is the second of at wo-part study of the quality of car horn sounds. It aims to provide insights into the design of newsounds. It is based on the assumption that hearing acar horn sound warns road users because theyr ecognize the sound of ac ar horn, i.e.(More)
