TABLE 3.

The Amount of Spatial Release From Masking in Decibels (Values in Parenthesis Are Standard Deviations) Under Noise and Speech Masker Conditions Across Subject Groups

Masker Type	Older Nonmusicians	Older Musicians	t(p)	Young Nonmusicians	Young Musicians	t(p)
Noise	0.84 (0.93)	1.42 (0.92)	−2.68 (0.009)	1.10 (0.78)	1.02 (0.79)	0.40 (0.690)
Speech	5.68 (1.34)	5.51 (1.17)	0.57 (0.572)	3.55 (2.14)	3.99 (1.28)	−1.09 (0.281)
t(p)	−17.30 (<0.001)	−20.09 (<0.001)		−5.41 (<0.001)	−14.26 (<0.001)

Two-tailed paired t tests and independent two-sample t tests were used for examining the differences between maskers and groups, respectively.
