The I/O function of at the CF of 16 kHz. The input sound pressure ranged from 20 to 100 dB SPL. (a) in the active (i.e., the OHCs are functional with maximum forces of 155 nN) and passive states. (b) Gain of in the active state relative to that in the passive state. Calculated result, solid line; experimental result by Ren and Nuttall [19], dotted line with closed circles; experimental results by Overstreet et al. [25], dotted lines with open circles and squares.
