Averaged prediction error (NRMSD) between the predicted and perceptual data. The mapping and prediction errors of calculated results are shown in italic and bold, respectively.
| Experiment | Modification | Condition | Fitting parameter | NRMSD (%) |
|---|---|---|---|---|
| A | ILD expansion | BB | bILD | 4.5 |
| LO | 4.8 | |||
| HI | 7.8 | |||
| B | Spectral magnitude smoothing | ipsilateral, constant ILD | bξ & w | 4.9 |
| C | ILD contrast compression | ipsi | bξ & w | 4.0 |
| contra | bξ & w | 4.0 | ||
| D | Spectral magnitude smoothing | bi | 4.8 | |
| ipsi | 3.7 | |||
| contra | 4.2 | |||
| E | Reverberation reduction and spectral magnitude smoothing | High spectral detail (B = 0) | bILD TSD & bγ | 3.3 |
| B = 1 | 4.7 | |||
| B = 4 | 6.4 | |||
| B = 16 | 3.1 | |||
| Low spectral detail (B = 64) | 3.0 |
