Attack/Recovery Time Settings

1) Ensure that Attack/Recovery Time 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. "Attack/Recovery low 50, high 90").
2) Stimulus Selection:

Pre-stimulus: Set the pre-stimulus time in milliseconds using the corresponding slider. The
pre-stimulus sets the low level stimulus prior to presentation of the higher level signal which
prompts the hearing aid compression to be activated and turn down gain.

Time scale: Set the time window of the full recording in the Time scale slider. This indirectly
also sets the duration of the high level stimulus, which is always 50% of this time window.
Example: A 300mS time window setting will provide a test where the high level stimulus has a
duration of 150mS.

Stimulus frequency: Select the preferred frequency for the Attack/Recovery measure using the
slider.
3) Attack/Recovery Levels:

Low: Select the low stimulus level to be present at the beginning and the end of the test.

High: Select the high stimulus level to be presented in a time window during the test.
Note: The test reports the output of the hearing aid, which will of course be different from the
stimulus levels set here.
