The average SRT scores, PPD, and the subjective ratings for both levels of intelligibility and for both masker types.
| Intelligibility | Fluctuating | Single talker |
| SRT | SNR (SD), dB | 50% | −11.2 (1.5) | −12.6 (1.9) | 84% | −5.7 (1.5) | −6.0 (2.8) |
| Pupil | PPD (SD), mm | 50% | 0.23 (.16) | 0.29 (.16) | 84% | 0.16 (.12) | 0.22 (.16) |
| Subjective | Effort (low = 0–high = 10) | 50% | 6.9 (1.5) | 6.7 (1.3) | 84% | 4.7 (1.7) | 5.3 (1.6) | | Performance (low = 0–high = 10) | 50% | 5.5 (1.4) | 5.4 (1.0) | 84% | 7.1 (1.0) | 6.9 (1.2) | | Motivation (low = 0–high = 10) | 50% | 8.0 (1.4) | 7.9 (1.7) | 84% | 8.6 (1.3) | 8.6 (1.3) |
