Measurement results (diamonds) for longitudinal (top) and transverse impedances (bottom) together with the predicted impedance spectra (lines) of the simplified and realistic MAFIA T3 model respectively. The European definition of the shunt impedance R=Ueff2/2PV is assumed with Ueff=effective voltage, PV=power loss.

Sound power (dB) at the entrance to the cochlea relative to P0=10-18W for an incident plane wave intensity of 10-12W/m2. All individuals have been modeled by using the model defined by Rosowski [23] and the cochlear input impedance (Zc) of Aibara et al. [43]. Solid blue line, modern human; solid green line, chimpanzee 3D CT; solid red line, AT-84; dashed red line, AT-4103; dashed- dotted red line, Cranium ...

Cell growth on the sensor chip captured with our impedance-to-frequency converter (black solid line, left axis) and actual impedance at 10 kHz measured simultaneously via a LCR meter connected to on-chip electrodes (red solid line, right axis). Also shown are data from a control experiment without cells (dashed lines).
