Speech Test Results tables are replaced with the Speech Audiogram and Speech
Rollover Results Table.
The SRT score will be plotted on the Speech Audiogram at 50% on the
corresponding hearing level. Word recognition scores will be plotted on the
Speech Audiogram based on the hearing level at which the test was performed
and the score that was achieved. As additional WRS are plotted, the Pello will
determine PI-PB (Performance Intensity Function for Phonetically Balanced
Words) function. PIPB function is tested by comparing two (2) or more WRS
results performed at different intensities. It will automatically calculate and
display in the table the Rollover index when enough data is available.
NOTE
: If the SRT was testing Left/Right routing selected, the symbol plotted on
the Speech Audiogram will be which indicates the stimulus was presented to
both ears.
Navigation Menu
The Navigation menu has the same functionality and selections as the Speech
Status display and the addition of the New Curve menu item.
New Curve
The new curve button on the Navigation Menu starts a new curve on the speech
audiogram. The current data is maintained and a group of WRS data will be
plotted on the same graph. New curve results will be displayed in the Speech
Rollover Results table when enough data is available.
NOTE
: Only curves with PI-PB Rollover will be displayed in the rollover
results table.
More Test Type
The “More” test type button calls up a menu of special tests that are included
with the Special Test and/or Speech Plus modules. If the Pello is not licensed for
these options, no additional menu items appear when the More Test Type button
is pressed. See Chapter 9, Optional Features and Functionality, for more
information.
