FIG. 5. — (Color online) Down-swept tympanogram for normal infant N. Row 1: absorbance (left) and group delay (right) typanograms D_p versus frequency and air pressure. Row 2: LP (left) and HP (middle) filtered absorbance tympanograms versus air pressure, with peak absorbance and TPP values in left panel and half-tympanometric widths TWn and TWp of the LP tympanogram in the middle panel. Row 2 (right): absorbance tympanogram versus frequency at TPP, P_pt, and P_nt compared to ambient absorbance. Row 3: LP (left) and HP (middle) filtered group-delay tympanograms versus air pressure. Row 3 (right): Tympanometric group delay D_p at TPP, P_pt, and P_nt compared to ambient group delay. The diamond markers in each left and middle panel of rows 2 and 3 air pressure at TPP, TPP − TWn, and TPP + TWp.
