Abstract
The reduction of the auditory response to one tone due to the simultaneous presence of a second tone is known as two-tone suppression. This nonlinear cochlear response was first described by Galambos and Davis (1944) in electrophysiological recordings from the cat auditory nerve. Since then two-tone suppression has been extensively studied in cochlear afferents of mammals (Nomoto et al., 1964; Kiang et al., 1965; Hind et al., 1967; Sachs and Kiang, 1968) and also of amphibia (Frischkopf and Goldstein, 1963; Feng et al., 1975), birds (Sachs et al., 1974) and reptiles (Holton and Weiss, 1978). Two-tone suppression seems to be demonstrable in all well-studied cochlear fibers, for suppressors at frequencies on both sides of the tuning curve (Sachs and Kiang, 1968; Sachs, 1969; Abbas and Sachs, 1976), and has also been observed in guinea pig inner hair cells (Sellick and Russell, 1979).
