CHEN2011 - Fast excitation pattern estimation

Usage:

[Ldn,E,Cam,CF] = chen2011(inputF,inputLdB)

Input parameters:

inputF vector of input frequency values
inputLdB vector of input level

Output parameters:

Ldn loudness
E excitation at the output of the passive filter
Cam ERB-number in Cams (Glasberg and Moore, 1990; Moore, 2003)
CF center frequency of auditory filters

Description:

chen2011 provides a fast way of loudness estimation.

Optional parameters:

'HLcf',HLcf parameters to simulate hearing loss: audiogram frequencies
'HLohcdB0',HLohcdB0 parameters to simulate hearing loss: OHC loss at audiogram frequencies
'HLihcdB0',HLihcdB0 parameters to simulate hearing loss: IHC loss at audiogram frequencies
'cambin',cambin spacing [ERB] between successive auditory filter CFs
'flow',flow lowest center frequency of an auditory filter
'fhigh',fhigh highest center frequency of an auditory filter

Moreover, the model supports 3 flags for outer ear correction ('FreeField', 'PDR10', 'Eardrum').
