6.3 Measurements & Adjustments
Taking measurements in the Coupler Target and the Coupler EarSim screens is
just like taking measurements in the Coupler Multicurve screen. The only differ-
ence is the addition of the target (and possibly audiometric data) on the screen.
Any measurements taken in one of these screens will show up in the other
screens. For a detailed explanation of the measurements available in all coupler
measurement screens, see Chapter 3.
The Coupler Multicurve and Coupler Target screens will show identical mea-
surements. The Coupler EarSim screen converts these measurements into simu-
lated real-ear measurements, so their numerical values will be different than
those displayed in the other coupler screens.
