Top panel shows the mean TPP-minus-tail differences for absorbance tympanograms for positive-tail (PT) and negative-tail (NT) differences for downswept (AtD) and upswept (AtU) tympanograms (N=57 ears). Error bars for both panels represent ±1 SE. Bottom panel shows the mean absolute value of the test-retest difference for absorbance TPP-minus-tail differences for PT and NT for AtD and AtU tympanograms. Symbols are jittered on the frequency axis in both panels for clarity.
