| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Perceptually relevant representations of timbre using two dimensional shapes are investigated aiming at establishing a framework for sound visualization based on human perception characteristics. A preference test of matching shapes to sounds was conducted using eleven sound stimuli having different prototypical power spectra and nine shapes. The results indicated that matching shapes were clearly divided into two classes depending on periodicity of the presented sounds. Perceptual correlates of shape selection were seemingly based on complexity and sharpness, while they are only subjectively defined. A set of objective descriptors of shapes based on complex number representation of their contours were introduced for further investigations on physical correlates of MDS results. These investigations indicated that normalized square root of area ratio to contour length and kurtosis have reasonable correlations with MDS axes. | |
