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').
