Abstract
A recent paper by Nuttall and Dolan [J. Acoust. Soc. Am. 93, 2061–2068 (1993)] on intermodulation distortion in the cochlea concluded that electrical quadratic distortion (f2−f1) came predominantly from inner hair cells (IHCs). However, they suggested that the outer hair cells provided the mechanical input that caused this even‐order distortion. The data reported here describe the nonlinear components in the gross electrical and acoustic emission responses of the gerbil and suggest a mechanism by which odd‐order distortion could be generated by modulation of the fast phasic motile response of outer hair cells (OHCs) by the even‐order distortion signal.Keywords
