Impedance and admittance tympanometry. I. Experimental approach.
In this experimental study a procedure is developed which enables the conversion of susceptance and conductane tympanograms to reactance and resistance tympanograms. Special attention was given to the subtraction of the ear canal admittance. The procedure was applied to bell-shaped and W-notched susceptance and conductance tympanograms. Computed reactance curves showed always an inverted-V shape, computed resistance curves were always flat.
