3.2 Speech Reception Threshold in Noise
Individual SRTs along with group means (SD) for the co-located, SeparatedS0NNH, and SeparatedS0NSSD test conditions in the SSD group are shown in Figure 1. When unaided, mean SRTs (SD) were −4.14 (1.95) dB SNR in the Co-located condition, −2.43 (2.76) dB SNR in the SeparatedS0NNH condition, and −7.14 (1.86) dB SNR in the SeparatedS0NSSD condition. A within-subject ANOVA analysis revealed a significant effect of the three conditions on SRT (F=15.13, p<0.05), whereby SRTs in SeparatedS0NSSD were the lowest followed by SRTs in the Co-located condition, and SRTs were largest in the SeparatedS0NNH condition.
