3.1 Speech Discrimination Scores in Quiet
When fitted with a BCD, the mean (SD) SDS in quiet for patients with SSD
significantly improved from 32% (16.42%) to 78.86%
(12.64%),
(t=−12.73, p<0.05). However, the SDS in aided condition was
lower than that in NH participants (independent t- test, aided vs
NH, 78.86% (12.64%) vs 98.86% (1.57%), t=−4,15, p<0.05).
The SDS data for each participant are presented in the table.
