Results are shown for OAE measurements (monaural stimulation) and ABR measurements (monaural and binaural stimulation). The fifth and sixth columns show the 95 % confidence interval (lower and upper limit) of the difference distribution of lag suppression below vs. above the echo threshold.

*p < 0.05; **p < 0.01; ***p < 0.001 Asterisks denote confidence intervals significantly larger than zero
