5.3.2 SPEECH AUDIOMETRY WITH LIVE VOICE SIGNAL

With a live voice signal it is possible to perform either threshold measure-
ments or discrimination tests and to present the stimuli via Air, Bone or Free
Field. Please refer to sections 7.1 and 7.2 for details concerning threshold
measurements and discrimination testing in speech audiometry.

1. Plug the headphones, patient microphone, patient response signal,

bone conductor and monitor headset (or Talk-Over microphone) into
their respective connectors on the rear panel.

2. Connect the MIDIMATE 622 to the mains.

3. Switch on the instrument by pressing the power switch on the right side

panel.

4. After the power-up test has been completed, the audiometer will

automatically access User Test 1. Proceed with this preprogrammed
test if suitable or press

MENU

to access any other suitable User Test or

press

MENU

again to access the Select Function Menu and set up your

own test as described in 4. Test Setup.

Output may be Air, Bone or even Free Field but

Micr.

must always be

selected as input.

5. Adjust microphone level by reading from the word list while at the same

time pressing the

MICROPHONE

pushbutton and turning one of the

rotary knobs so that the stimulus level on the Stimulus LED deflects up to
O VU. See 5.1.3 on page 20 for detailed description.

MICROPHONE

6. Place the patient in sound cabin facing away from the audiometer.

7. Instruct the patient to repeat the words he hears and test each ear in turn

(using

L/R Shift

).

L/R SHIFT

Refer to section 7.3 for further details on live voice testing.

5.3.3 SPEECH AUDIOMETRY WITH PRERECORDED SIGNAL

With a prerecorded signal it is possible to perform either threshold
measurements or discrimination tests and to present the stimuli via Air, Bone
or Free Field. Please refer to sections 7.1 and 7.2 for details concerning
threshold measurements and discrimination testing in speech audiometry.

1. Plug the headphones, patient microphone, patient response signal,

bone conductor and monitor headset (or Talk-Over microphone) into
their respective connectors on the rear panel.

2. Connect the tape recorder or CD player to the socket marked Tape 1 on

the rear panel. If masking with a prerecorded signal is to be used,
connect the signal to the socket marked Tape 2.

3. Connect the MIDIMATE 622 to the mains.
