Taking Tympanogram
Cancel
Once an adequate seal is detected the tympanogram measurement is made. This takes about 3 seconds. It is
important not to move the probe and to ask the patient to remain very still during the test.
When the tympanogram is complete the instrument will perform the reflex test(s), if selected. By default this
test is only performed if a peak is found in the tympanogram. This and other reflex test options may be changed
in the CONFIGURATION menu, see Section 6.
Before starting the reflex test the ear canal pressure will be set to the value that gave the peak compliance
during the tympanogram test. The instrument will then step through the tone frequencies and levels set in the
CONFIGURATION menu searching for a reflex response.

The display changes to show the frequency and level being used, starting with the lowest frequency and level

When the measurement is complete the indicator on the instrument changes from flashing green to steady
green. The display confirms that the test has been completed along with the instruction WITHDRAW PROBE.
Remove the probe from the patient and after a short period the tympanogram will be displayed.
