(Color online) Behavioral hearing thresholds for SOAE+ (crosses, n = 16) and SOAE− (circles, n = 18) subjects. Symbols represent mean data and error bars are ±SD of the mean. Global thresholds were assessed once for the majority of subjects. Significantly better thresholds are observable inthe SOAE+ group at 0.125, 0.250, and 0.5 kHz (marked by asterisks, p< 0.05).
