5.2.4 Speech Audiometry with Wave Files
If Wave is selected by the speech signal selector (11) a menu will pop-up with
the available word lists, stored on the SD memory card. A word list can be
selected by using the level controls to scroll through the list. A list can be loaded
by pressing the Stimulus button. The word list will then be displayed on the
speech audiometry screen.
The level is displayed as a numerical value at the top of the screen. The level
can be changed with the level controls (1) on both sides of the instrument.
Before starting the playback of the wave files, the first word can be selected by
the Frequency Up and Down buttons (4) and (5). Press the functional button
Play (7) to start or pause the wave file playback.
The procedure for the SRT, WRS and UCL test is the same as the procedure for
CD or microphone testing. For the SRT test a word needs to be selected in the
wordlist by the frequency up (4) or down (5) key. When the Play button (7) is
pressed, the selected word is presented.
For the WRS test score, tally the correct words by pressing the frequency up (4)
key and the incorrect words by pressing the frequency down (5) key. The next
word will be played back automatically. Press the functional button Pause (7)
to interrupt the playback.
The percentage of the speech discrimination score will be displayed and stored
in the speech table or audiogram as soon as the Store button (3) is pressed.
Press the functional button List (6) to load another word list.
