Partially masking a tone shifts its perceived pitch upward

Evidence

Pitch shifts of pure tones can occur if additional sounds that produce partial masking are presented. In the demonstration, a pure tone with 2.7 kHz is partially masked by a narrow-band noise at 2 kHz, both with a level of 65 dB. First you will hear the pure tone alone, and then the tone plus noise. This sequence is repeated three times. When the tone is partially masked by the noise, the pitch is perceived to be higher. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing.

Categorization

  • DEFINE: Concrete instance of how masking alters pitch perception, a key psychoacoustic concept.
  • corroborated: 2 independent passages support this claim — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing. Eberhard, Psychoacoustics- Facts and Models, 3275
  • XREF: connects to: Partial masking shifts pitch away from the masker’s spectral region; Raising a tone’s level lowers low-frequency pitch but raises high-frequency pitch; Adding higher partials can drop the perceived pitch of a tone — Eric J.
