Document Summary
Periodicity pitch of a complex stimuli can be perceived with or without. Even when no periodicity present at the period of the missing f0, the missing. Not due to spectral energy or envelope periodicity or harmonic spacing. Place theory says pitch relates to excitation pattern. Cannot explain pitch perception because a sound of a particular pitch can be perceived even when there is no energy at the frequency corresponding to the pitch. Volley (temporal) theory says that time pattern of neural impulses determines pitch. Interval between impulses related to period of stimulus. Cannot explain pitch perception no phase locking to stimulus frequencies above 5khz. Pitch perception probably involves both place and volley theory. When auditory system is stimulated at high levels with a tonal complex, ss report hear pitches at: These sensations reflect the nonlinear properties of the peripheral auditory system. Cubic difference tone: 2f1 f2 (2 x 840) 1000hz = 680hz.
