The actual sample size varied slightly across measures and is indicated in the second column (N). The p-value for paired-sample t-tests of these two means is also provided as is the Pearson-r correlation coefficient between test and retest. In both cases, significant t-test p-values and r-values are marked with an asterisk. Given 50 measures, the criterion p-value for statistical significance using Bonferroni adjustment for multiple comparisons is p < 0.001 (i.e., 0.05/50). Units for each measure are dB unless indicated otherwise.
