This compliance (static acoustic admittance) is represented by the highest peak of the curve on the graph (Figure 1). Maximum compliance of the middle ear system occurs when the pressure in the middle ear cavity is equal to the pressure in the external auditory canal. Compliance is plotted vertically on the tympanogram, and is measured in ml or mmho. ![]() A tympanogram provides information regarding the compliance of the middle ear system (how well sound passes through the eardrum to the middle ear system), ear canal volume, and middle ear pressure. To understand the types of tympanograms, you should first understand the meaning behind the parts of the graph itself. Can you run down the list of common tympanogram types? Answer As a speech pathologist, I routinely come across reports documenting tympanogram results.
