Ensure that Directionality is marked in the left hand side of the screen. The name of the test will
then appear in the Name of selected test section.
Note the option to write a new name for the test in this section (e.g. "Directionality check")
• Stimulus Selection
 Input Level: Set the input level using the slider.
 Stimulus type: Select a stimulus using the dropdown list.
 Smoothing Index: You have the option to smooth the measured curve using the slider (see
section 0 for details). The higher index number selected the more smoothing is applied.
 Start Frequency and Stop Frequency: Select the preferred frequencies using the sliders.
These may for example be set so that they correspond with the hearing aid gain handles (e.g.
if the hearing aid goes up to 8000 Hz there is no reason to measure beyond this frequency).
To avoid low frequency noise you may wish to set the slider to a start frequency of 200Hz.
 Measurement time (in seconds): Duration for the measurement can be set using the slider.
This is only relevant for broad band signals. A number of seconds can freely be selected
between 1 and 1200. By default the measurement time is the same for all signals.
3) Recording Method:
 Resolution (of frequency): Select the preferred resolution in the dropdown. The higher the
resolution the slower the measurement.
