TABLE I.

Estimated area, length, and volume repeatability for adult subject B for ambient and tympanometric tests. The column ΔS lists percent change of the estimated area for test 2 relative to test 1, and similarly for the column ΔL for estimated length and ΔV for volume (as product of estimated area and length).
