Figure 6

Comparison of the effects of postural changes and ear-canal static pressures on energy reflectance. The difference in energy reflectance between the upright and tilted −45° postures reported in Fig. 3 are represented by the mean measurement plotted in solid black and the 25–75% range (shaded gray). Margolis et al. (1999) report the means of measurements of reflectance made at ambient ear-canal pressure and at an ear-canal pressure compensated to match the tympanic peak pressure measured via tympanometry. These reflectance measurements were extracted from Fig. 7 of Margolis et al. (1999), converted to energy reflectance, and the difference between the two conditions (compensated minus ambient) is plotted in the dashed line.
