Mean sentence reception thresholds (SRTs) and the standard deviations (in brackets). Paired sample t-tests were conducted to compare SRTs obtained in the aided and unaided conditions; statistically significant differences between aided and unaided SRTs were found in all test conditions (*P < .001, 2-tailed).
