Abstract
Upon stimulation of the mammalian ear by two tones of frequencies f1 and f2, distortion-product otoacoustic emissions (DPOAEs) can be measured at 2fl-f2 in the ear canal. These DPOAEs are vulnerable to cochlear insult; in small mammals 2f1-f2 DPOAEs below stimulus levels of 60–70 dB SPL disappear more rapidly post mortem, and are considerably more vulnerable to traumas such as asphyxia and aminoglycoside poisoning, than those above this level (Schmiedt & Adams, 1981; Kemp & Brown, 1984; Schmiedt, 1986; Lonsbury-Martin et al., 1987; Brown et al., 1989).
