The I/O function of the 'cascade of asymmetric resonators with fast-acting compression' (CARFAC) modelis calculated by the RMS of the out in response tones at intensities from 10 to 100 dB SPL at the CFs of 0.5, 1, 2 and 4 kHz. The nonlinear compressive shape of the I/O function represents the cochlear mechanical compression.
The Input-Output (I/O) functions at a center frequency of 500 Hz
The Input-Output (I/O) functions at a center frequency of 1 kHz
The Input-Output (I/O) functions at a center frequency of 2 kHz
The Input-Output (I/O) functions at a center frequency of 4 kHz
