VICENTE2020_INTERNALNOISE - calculates internal noise level
Usage
[IN_L,IN_R] = vicente2020_internalnoise(fc,f0,Aud_L,Aud_R,N,B,Nlim,eta,max_OHC)
Input parameters
| 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 |
Description
vicente2020_internalnoise simulates the internal noise based on the input audiograms by calculating the IHC and OHC loss, taking into account the external noise level.
