抄録: Generally pitch is strongly related to fundamental frequency. However, we experience the different pitch when we listen to the sound , produced by different musical instruments, which has same fundamental frequency. It is conceivable that the height is not only determined by fundamental frequency. It was reported that the second harmonic influences the pitch perception by E. Zwicker and H. Fastl (1999). Roelf J. Ritsma (1967) showed that the lower harmonics had an influence on pitch. These studies showed that pitch of harmonic complex sounds was affected by the higher harmonics. However, these researches do not show the relation between the strength of harmonics (spectral tilt) and pitch in detail. Therefore, we investigate pitch perception of complex sounds with spectral tilt. We confirm that pitch is different depending on change of spectral tilt. We investigate the physical correlates of pitchperception in addition to the fundamental frequency.We used two groups of stimuli to investigate existence of pitch perception change depending on spectral tilt, and to investigate the factor of pitch perception. In experiment 1, we presented stimuli according to the pitch with stimuli consisting of same spectral tilt and different fundamental frequency. In experiment 2, we presented stimuli according to the pitch with stimuli consisting of different spectral tilt and same fundamentalfrequency. We did a comparison experiment of the pitch perception with all stimuli. It was difficult to compare stimuli of two groups varied under different conditions. Therefore, we measured psychological distance of all stimuli. We constructed a perceptual space using by Multi-Dimensional Scaling (MDS) ( Experiment 3 ). We applied results of experiment 1 and 2 to the perceptual space with a multiple regression analysis. Based on this investigation, weconsider whether the pitch perception factors in each condition are different. Based on the perceptual space, we consider the physical correlates which are strongly related to the pitchperception of the stimuli in which spectral tilt is different.
