5.2.3
Preparing for air conduction testing
Headphones, insert phones
Make sure that the headphones and insert phone(s) are properly connected.
Connection to the device
See
for a description of how to connect headphones and insert phones to the device.
Fitting on patient
•
Place the patient facing away from the device, in a sound booth, if one is available.
•
Set the switch on the Talk Back microphone to ON and set the level of Talk Back (
).
•
Fit the headphones on the patient, with the red phone on the right ear.
•
Choose the ear with the better hearing to be tested first.
Instructing the patient
•
The patient will be hearing brief tones.
•
The tones may at times appear to be very weak.
•
Instruct the patient in how to use the patient responder (
).
•
The patient should press the patient responder as soon as the tone is heard, even if it is very weak.
5.2.4
Preparing for bone conduction testing
Make sure that the bone conductor is properly connected.
Fitting the bone conductor on the patient
When you fit the bone conductor on the patient:
•
Instruct the patient in what you are about to do.
Note
•
The bone conductor cable and insert phone cable must not be removed or tampered with while
MADSEN Itera II is powered on. Either disconnect the bone conductor or insert phone entirely from the
instrument, or make sure that the instrument itself is disconnected from the power source.
•
If a sound booth is not available, place the patient facing away from MADSEN Itera II. This is to avoid visual
clues during testing.
•
If applicable, set the switch on the Talk Back microphone to ON and set the level of Talk Back.
•
Position the bone conductor/vibrator so that it rests comfortably against the mastoid bone (behind the ear)
and is not in contact with the pinna, or against the patient’s forehead.
•
If MADSEN Itera II is calibrated for this, see
SETUP
,
to choose between Forehead and Mastoid,
depending on the preferred placement of the bone conductor.
Testing with masking
If you intend to use masking, either use the mono insert phone (recommended) or fit the headphones so that the red
(right) phone is applied to the poorer ear for masking, and the other phone is applied to the patient's temple region, leav-
ing the test ear uncovered.
