Figure 4. — Each frequency-band demonstrated significantly lower TEOAEs for Metabolic and Metabolic + Sensory ears, with well-preserved TEOAEs in the 1 and 1.5 kHz bands for Sensory ears compared with Older-Normal ears. Bar plots show the average frequency-band TEOAE-SNR (a) and TEOAE Confidence (b) plotted with standard error of the mean bars for each phenotype, after residualizing variance related to ME compliance, participant age, and participant sex. Each set of bars is grouped by phenotype and shows the TEOAEs measured at 1, 1.5, 2, 3, and 4 kHz frequency-bands in ascending order. Asterisks indicate significant within-band phenotype differences in the GLMM regression analyses (Bonferroni-corrected α = .05 ÷ 6), with colors indicating the significantly different phenotypes: gray-Older-Normal (ONH), green-Metabolic (MET), red-Sensory (SEN), blue-Metabolic + Sensory (MET+SEN). TEOAE = transient-evoked otoacoustic emission; SNR = signal-to-noise ratio; ME = middle ear.
