Figure 8

Top panel shows the mean equivalent admittance level at the tympanometric tails for the downswept (|Yt|D) and upswept (|Yt|U) tympanograms for the positive tail (PT) and negative tail (NT) conditions. Admittance level is normalized to 0 dB for an admittance magnitude of 1 mmho. Bottom panel shows the mean equivalent admittance phase for PT and NT conditions as a function of frequency for the downswept (ϕtD) and upswept (ϕtU) tympanograms (N=57 ears). Error bars for both panels represent ±1 SE. Symbols are jittered on the frequency axis for both panels for clarity.
