Previous studies have shown that the time interval marked by the onsets of two successive pure tone bursts is perceived to be longer when the second sound marker is lengthened. The present study examined whether this phenomenon appeared in a more natural setting in which the time interval was marked by instrumental sounds with complex temporal and spectral structures. Real piano sounds and synthesized sounds that simulated either just the temporal structure of the piano sound or both its harmonic and temporal structures were used as sound markers. Lengthening the second marker increased the perceived duration of the interval, as in previous studies, but only in limited cases, and this did not occur in an experiment in which only the synthesized piano sounds were used. Thus, the effect of sound durations was weakened with the new series of sounds. Characteristics of piano sounds that were not captured in the synthesized sounds seem to have played an important role in duration perception.
