Figure 9. Admittance magnitude (Y) and phase-angle (f) tympanograms recorded at 660 Hz from a normal middle ear (left panel), from an ear with ossicular abnormality (middle panel), and from an ear with middle-ear effusion (right panel) (taken from Van Camp et al., 1986). The corresponding susceptance (B) and conductance (G) tympanograms are shown for comparison.
