RECD Settings

1) Ensure that RECD 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. "RECD with SPL probe")
2) Select the preferred Coupler type.
Choose between:

2cc coupler (IEC 126)

Ear simulator (IEC 711)
The volume of the IEC 711 is more similar to the volume of a real ear than the 2 cc coupler.
Note: No predicted values are available for Ear simulator (IEC 711). If selecting Show
predicted curve the values displayed on the graph will be based on 2 cc coupler values!
3) Stimulus Selection:

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.

Continuous: This check box allows you to make the measurement ongoing rather than a single
sweep. This may, however, also be done in the front screen using the continuous button:
When continuous is ticked, the stimulus and recording will continue until you press the STOP
button. This can be practical either if you want to change the settings of the hearing aid and
observe the changes in hearing aid performance.
