bramslow2004_specloudn
Specific and total loudness from an excitation pattern
Usage:
[E_Vector, TotLoudn]= bramslow2004_specloudn(E_Vector, E_0, E_TQ, E_UCL,HTLL, NoChan, E_Beg, E_End, Binaural)
Input parameters:
| E_Vector | Excitation (in dB) per ERB band. |
| E_0 | Excitation (in dB) per ERB band at the SPL of 0 dB. |
| E_TQ | Excitation (in dB) per ERB band at the hearing threshold (TQ). |
| E_UCL | Excitation (in dB) per ERB band at the UCL. |
| HTLL | Hearing threshold levels interpolated along the ERB scale to obtain SPL (in dB) of the 4152 coupler. |
| NoChan | Number of output channels (equally distributed on the ERB scale). |
| E_Beg | Lowest ERB rate considered (in Cams, typically 3 Cams). |
| E_End | Highest ERB rate considered (in Cams, typically 32 Cams). |
| Binaural | Flag considering the type of listening. If true, binaural listening is assumed. If false, monaural listening is assumed. |
Output parameters:
| E_Vector | Specific loudness (in sone) in the ERB bands. |
| TotLoudn | Total loudness (in sone) across all ERB bands. |
