Level of the DPOAE produced by equal-level primary tones of SPL located in the frequency regions indicated. For each designated frequency region, the results for three pairs of primary tones were averaged; see text. Only data from Caucasian and Hispanic subjects included. Flags designate the standard errors of the mean.
Strength of the TEOAE responses evoked by a click of about SPL. The averaged TEOAE waveform was analyzed in several narrowbands as well as wideband. For the narrowband conditions, the levels shown are for 0.1-octave bands centered approximately on the frequency values shown.
Effect sizes for the sex and ear differences shown in Figs. 1 and 2. Positive effect sizes correspond to the mean OAE being stronger in females than males, or stronger in right ears than left ears; Ns for sex differences are shown in Figs. 1 and 2; Ns for ear for female∕male, at .
Correlations between TEOAEs and DPOAEs, shown separately for the various frequency regions, the two ears, and the two sexes. Ns for for Lt vs Lt and Rt vs Rt, at ; Ns for for Lt vs Lt and Rt vs Rt, at .
Correlations between the two ears for DPOAEs and for TEOAEs measured at various frequencies. Ns for for females∕males, at ; Ns for for females∕males, at .
