6.2.2 Performing Speech Testing
Use the function button for Speech on the right side of the tone screen (16) to
switch to speech testing. The speech test screen will open, and the unit will
default to the right ear and the level will be set to the default value.
The speech recognition threshold (SRT) is a test indicating the lowest level in
which speech is understood using a closed set of spondaic words. Speech
testing can be done via recorded speech test material from CD or wave files or
with the microphone and live voice using standardized word lists.
Ask the patient to repeat each word. Often times a carrier phrase such as, “Say
the word _______” may be used. The patient should sit at a distance of at least
1 meter from the device. Additionally, any obstructions which may interfere
with the placement of the earphone cushions on the ear (i.e. hair, eyeglasses)
should be removed. Ensure the headphones are put on correctly. Adjust the
headband of the headphones so that the receivers are at the correct height (the
sound output grid should be placed directly over the ear canal).
Select the ear to be tested by pressing Right, Left, or Both by the function
button (9) on the control panel underneath the screen.
Next, select the transducer to be used, Phones, Insert, or Speaker by pressing
the Transducer button (10). Toggle to the required signal by the selector button
(11) to MIC/CD/Wave.
6.2.3 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 function button (11).
