摘要：
Cells isolated from the organ of Corti were held in the microchamber configuration and their mechanical impedance was measured in a broad frequency range (0.48-50 kHz). This was achieved with a more sensitive version of a previously presented method employing magnetically actuated probes. Preliminary data suggest that axially loaded outer hair cells exhibit a purely viscoelastic impedance composed of a spring and a frequency dependent damper. The spring constant compares with known values.
