DATA_JOERGENSEN2011
Experimental data from Joergensen and Dau (2011)
Usage:
[acrossSubdSRTs,std_acrossSubSRTs] = data_joergensen2011(flag)
Description:
data_joergensen2011 returns measured change of SRT tested by Joergensen and Dau (2011). Average and standard deviation across listeners.
The flag may be one of:
| 'fig5' | : The measured change in SRT (open squares), averaged across 6 normal-hearing listeners, as a function of the reverberation time, T30 (0s, 0.4s, 0.7s, 1.3s, or 2.3s). The mean SRT in the reference condition was -3 dB. Model predictions are indicated by the filled squares. The linear correlation coefficient (q) and RMSE is indicated in the upper left corner. |
| 'fig6' | : DSRT (left ordinate) as a function of the over-subtraction factor a (0, 0.5, 1, 2, 4, or 8) for 4 normal-hearing listeners (open squares) and sEPSM predictions (filled squares). The right ordinate (with a reversed scale) shows the corresponding sSTI values as filled gray circles. These values are, however, not converted to DSRT values since these would be outside the left ordinate scale. |
