I. Volume Displacement Of The Tympanic Membrane In The Sitting Position As A Function Of Middle Ear Muscle Activity

Abstract

For clinical measurements, the stapedius reflex responses have generally been recorded qualitatively using acoustic impedance bridges. The integrating microflow method devised by Elner et al. (1971) (see Fig. 1). has made it possible to record the direction of movement as well as the quantitative displacement of the tympanic membrane caused by a stapedius muscle contraction.
