Table 1.

Group average thresholds in dB SNR are provided for the four listener age groups in the two-talker speech and speech-shaped noise maskers. Standard deviation estimates are shown in parentheses. The average difference in threshold (in dB) between the two masker conditions is shown for each age group in the rightmost column.

	Speech-Shaped Noise	Two-Talker Speech	Two-Talker minus Noise
5–7 yrs	−0.5 (2.3)	5.4 (3.5)	5.9
8–12 yrs	−1.5 (2.2)	3.0 (1.7)	4.5
13–16 yrs	−3.8 (2.3)	−0.4 (2.0)	3.4
Adults	−4.2 (2.6)	−1.3 (1.8)	2.9
