5.2.3 Speech Audiometry with Microphone or CD player
Connect the microphone or CD player to the corresponding input (10). Select
the test ear (9) and MIC or CD as signal source by the functional button (11).
Make sure that the input signal is calibrated correctly, as described above. Select
the test SRT, WRS or UCL with the functional button (13).
For the SRT test familiarize the patient with a closed set of spondaic words at a
level loud enough for them to hear and understand. Begin the test and decrease
the level as the patient repeats the word. Once the threshold has been found
press the Store button (3) to save the result.
For the WRS test, the level remains fixed and correct or incorrect answers can
be entered by the Frequency Plus (4) and Frequency Minus (5) button. Once the
word list has been completed by the patient, press the Store button to save the
established WRS score. To clear the word counter, press the Reset key (6) on
the left side of the display.
For the UCL testing the level is increased until the patient indicates the level is
uncomfortable and the result can be saved by pressing the Store button (3).
