fc : center frequency of the model (vector)
f0 : audiometric frequency vector
Aud_* : left or right hearing thresholds @ f0
N : Noise level (scalar or vector)
B : Parameter of the internal noise defining the internal noise floor
Nlim : Parameter of the internal noise defining at which the internal noise level starts to increase with the external noise level
eta : defining the percentage of hearing threshold elevation due to OHC loss
max_OHC : maximum allowed for OHC loss
Output Parameters:
InternalNoise_* : Left/Right internal noise level @ model center frequency
IN_MaskerLevelDependentPart_* : Left/Right external noise level dependent part of the internal noise level @ model center frequency
Gamma : Transformation to convert dB HL into dB SPL @ model center frequency
