Abstract: To study whether pitch perception of medium-rank harmonic complex tones depended on the use of temporal fine structure information, fundamental frequency difference limens were measured. Target tone was presented in the absence or presence of a masker tone, which was filtered into the same frequency region with the target. The target and masker had different phase combinations and fundamental frequency differences. Results found that there were no significant effects of phase combination, but frequency region and fundamental frequency difference played significant roles in pitch perception. Analysis based on temporal model found that medium-rank harmonic complex tones could obtain good results of pitch perception, which is probably based on the use of temporal fine structure information. This study could help build mechanism of pitch perception under complicated sound scene.

Key words: harmonic complex tones, pitch perception, temporal model, temporal fine structure information
