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.
