Pitch shift of a tone burst(20 msec, 1, 000 Hz) with a preceding or trailing tone, was measured at different frequencies of preceding tone or trailing one and for several intervals between the preceding ore trailing tone and the test one. The results showed that pitch shift were upward for frequencies of preceding or trailing tones above the test tone, and downward for those below the test tone. The tendency of pitch shift is just in the opposite direction to that in the case of fatigue. The maximum shift was obtained when the difference of frequency between the preceding or trailing tone and the test one, was about 50 Hz. The effect of duration of the preceding or trailing tone on pitch shift was also investigated. The mechanism of pitch shift was discussed based on frequency analysis in the auditory system.
