Figure 3. Four examples (1B1G, 3B1G, 3B3G, and 5B3G) of normal susceptance (B) and conductance (G) tympanometric patterns recorded at 660 Hz, which are predicted by the Vanhuyse et al. (1975) model based on the relationship between reactance (X) and resistance (R). The admittance (Y) and phase-angle (fy) tympanograms also are shown for comparison (from Osguthorpe, 1986).
