Difference noise generated by ear nonlinearities can be heard before the test tone itself

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.
