Stimulus Intensities
Max. (dB HL)
When the list is shown, simply click on a specific intensity to select.
Then consider which adjacent intensities you wish to include. The
options will show according to the selected step size.
Note
•
You cannot extend the range to include stimulus levels
exceeding 100 dB HL in this test.
Whenever the stimulus intensity level exceeds 108 dB SPL, for
example when you select 100 dB HL at 500 Hz Ipsi, a warning will
appear, and the automatic test is paused. You will be prompted
whether to continue or skip to the next stimulus type.
Note
•
To avoid automatic testing being interrupted because
of high stimulus intensity levels when reaching the warning
limits, it is recommended that you set the max. intensity to
95 dB HL.
Increment (dB)
Select the step size to increment the stimulus intensity (Sound Pres-
sure Level) in increments of 10, 15, or 20 dB.
Default: 10 dB
Number of intens-
ities
Depending on the increment selected, you can select or deselect the
intensity. You can select up to three stimulus intensities. The com-
plete range of intensities available will appear when you deselect all.
