The middle ear impedance of a group of 25 subjects with normal middle ears was studied with the Zwislocki acoustic bridge. The basis for selection of test ears was carefully documented. Average and range of impedance measures were compared to recent data. The effects on impedance readings of operator error in the preliminary measurement of canal volume were also studied.
