What the ear perceives can diverge from sound’s physical components.

Evidence

This section concerns sounds that in some sense could be said to “deceive” the ear. Such sounds have a psychoacoustic realization that is not what might be expected from knowledge of their acoustic components. In other words, the subjective and objective realizations of sounds cannot be always directly matched up. While some of the examples given may be of no obvious musical use to the performer or composer, they may in the future find musical application in electronically produced music for particular musical effects where control over the acoustic components of the output sound is exact. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1568

Categorization

• DEFINE: Sets up the chapter’s organizing concept: subjective and objective realizations of sound don’t always match.
• corroborated: 2 independent passages support this claim — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1568
• XREF: connects to: The ear generates audible combination tones not present in the stimulus — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1571; Cubic difference tones arise inside the ear, not in the equipment — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing. Eberhard, Psychoacoustics- Facts and Models, 3354; Difference noise generated by ear nonlinearities can be heard before the test tone itself (+16 more)
