PERFORMING TYMPANOMETRY AND ACOUSTIC REFLEX TESTING
Amplivox YouTube video is available for assistance on how to run a test.
Before starting an acoustic reflex test, a tympanogram is performed so that the ear canal pressure will be set to the
value that gave the peak admittance. The tympanometry measurement is performed the same way as described in
section 4.9.2. The tympanogram will be followed immediately by an acoustic reflex test.
TROUBLESHOOTING:
By default, the acoustic reflex testing is only performed if a peak is found in the tympanogram. This setting can be
changed in the
SETTINGS
menu.
The acoustic reflex test screen consists of the preview of the
measured tympanogram. Underneath the graph, the tested ear, the
test frequency and intensity are listed. The reflex test starts with the
lowest frequency and level selected.
The instrument will then step through the tone frequencies and
levels set in the
SETTINGS
menu searching for a reflex response.
Please note:
If contralateral testing is enabled, the
ipsilateral reflexes are tested first.
When the measurement is complete the indicator on the probe
changes from flashing green to solid green. The display confirms that
the test has been completed along with the instruction
WITHDRAW
PROBE.
After the test has been successfully performed, three different actions can be taken. Selecting the right navigation key

takes you to

screen so that the data can be printed, stored or reviewed again.
