Sensitivity of YTM to changes in estimated ear-canal area and length for Adult A. Admittance measured at the probe tip (row 1). YTM for varying ear-canal dimensions: area only (row 2), length only (row 3), length and area varying by the same relative changes (row 4), and length and area varying by relative changes of opposite sign (row 5). For example, in row 5, a change of +20% in length was made with a change of −20% in area. This condition is termed the “−Area and Length” condition in the titles on row 5. These admittances are shown for the estimated area and length (0%) and for percentage increases and decreases relative to these reference dimensions.
