TABLE II.

Correlations and corresponding p values (with no post-hoc Bonferroni corrections for multiple comparisons) for three summary measures of ripple detection (the average threshold at ripple rates of 0.25 and 0.5 rpo, the average threshold at ripple rates of 2 and 3 rpo, and the interpolated ripple rate at which the threshold peak-to-valley ratio was 30 dB), and speech recognition measures.
