Second, and in contrast, each 3-dB increase in SNRs from 0 to +3 to +6 to +9 to +12 to +15 dB, in combination with one single-step reduction in RT from 0.9 to 0.6 to 0.3 s, yielded highly significant improvements in all scores (all p s ≤ .0082), with the exceptions of a significant change from 9 dB SNR in 0.9-s RT to 12 dB SNR in 0.6-s RT ( p = .0443) and a significant change from +12 dB SNR in 0.9-s RT to +15 dB SNR in 0.6-s RT ( p = .0112).
