Virtual pitch only arises under specific combinations of fundamental and lowest-component frequency.

Evidence

Not all complex tones from which the lower harmonics have been removed elicit a virtual pitch. Rather, specific combinations of fundamental frequency and of the frequency of the lowest component must occur in order to produce a virtual pitch. An existence region of virtual pitch, as displayed in Fig. 5.10, can be defined. It shows the fundamental frequency of a complex tone as a function of the lowest component, below which all spectral components were removed. In order to produce a virtual pitch, spectral components within the shaded area of Fig. 5.10 have to be presented. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing.

  • QUESTION: What mechanism explains the sharp existence-region boundary for virtual pitch? Worth digging into the underlying cochlear/neural basis.
