Pitch can be perceived at fundamental frequencies entirely below the hearing range.
Evidence
The f0 for the bottom note of a 64′ stop (C − 1) is 8.175 Hz, which is below the human hearing range but within the frequency range of difference frequencies that are perceived as beats (see Figure 2.6). Harmonics that are within the human hearing range will contribute to a perception of pitch at these f0 values, which are themselves below the frequency range of the hearing system. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1651
Categorization
- QUESTION: How far below 20 Hz does residue pitch hold, and does beat-rate perception really do the work here?
