Removing lower harmonics barely changes the perceived pitch of a complex tone.
Evidence
If the lower harmonics are removed from a complex tone, the pitch hardly changes. This means that the pitch of the (incomplete) harmonic tone without fundamental frequency usually corresponds closely to the pitch of its fundamental. The effect where the “residual” higher harmonics of a complex tone produce a pitch that corresponds to the low (fundamental) frequency has been termed residue pitch, low pitch, or virtual pitch. — Professor Dr.-Ing.

Categorization
- DEFINE: Defines virtual/residue/low pitch — the classic phenomenon that deleted fundamentals are still heard via higher harmonics.
- corroborated: 2 independent passages support this claim — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing. Eberhard, Psychoacoustics- Facts and Models, 708
