    Abstract

    Frequency and impulse responses were determined for isolated guinea pig outer hair cells by electrically stimulating the cells between two wire electrodes with white noise. Cells were attached to the bottom of a small culture dish at one end while the other end was freely moving. Results have the character of a damped second-order system, with a cut-off frequency of approximately 7 kHz. Correspondingly. impulse responses show a single narrow peak roughly 50 mu s wide and have the shape of the impulse response for a critically damped harmonic oscillator.
