8. Running Hearing Tests
The Osicus
can be used by any “
competent person
”,
technician, nurse or doctor, who has been
certified as having satisfactorily completed a competent persons audiology course.
Having become familiar with the hardware and software you are now ready to record
measurements.
Having previously either entered details for a new person or selected someone who has been
tested before, click on Run Test from the home screen. Before testing, you should ensure that the
subject’s ears are not blocked, the audiometer is connected and has been tested and the
headphones are correctly in place.
8.1 Calibration check
It is recommended that a calibration check is carried out at the beginning of the day prior to
patient testing to confirm Osicus performs as expected.
To do a calibration check, switch on the Osicus, start the software and move to the testing screen.
Enter Patient ID details if you want to save the calibration check.
Then either put the headset on an
“artificial
e
ar”,
with the response cable replacing the
response button unit or ask someone whose hearing level is known to put on the headset
(remove glasses and earrings if they interfere with the fit of the headset). Advise them to
press and release the button as soon as they hear the tone.
The
red
audiocup goes on the
right
ear and the
blue
headset on the
left
. Click on the
Test
button
to start the test.
On completion compare the audiogram with the previously recorded audiogr
am for that “artif
icial
ear” or test
person.
It is always possible for any threshold point to move up or down by 5 dB, but if almost all points
are further down the audiogram from previous results, the jack connections inside the booth
and outside the booth (if a booth is being used), plus the jack connections at the back of the
Osicus should be cleaned with an alcohol wipe and swiped in and out 10 to 20 times to clean
them.
The test should then be repeated. If this does not restore the thresholds, then a cable
problem might exist on the ear in question.
8.2 Patient Preparation
The patient should be prepared, prior to testing, by having them in a quiet stable environment
for 5 to 10 minutes. This is a suitable time to take a history, complete your pre-test
questionnaire and examine the ears for wax.
If they have recently been exposed to excessive noise, or have a cold prior to this appointment, a
note to this effect can be made in the comments section of the program.
