9.6 Preparing for a TEAOE measurement
9.6.1 Visual inspection of the ear canal
Check the external ear canal for wax with an otoscope and remove excessive wax to prevent the probe
opening from clogging which will inhibit testing.
9.6.2 Instruction of patient
Place the patient on a comfortable chair or on an examination table if necessary. Small children may feel
more comfortable sitting on a parent's or nurse's lap. Show the probe to the patient and then explain the
following:
The aim of the test is to screen the hearing organ for its functionality.
The tip of the probe will be inserted into the ear canal and has to make a good seal.
Multiple tones will be heard during the test.
No participation is expected from the patient.
Coughing, talking and swallowing will disturb test results.
9.6.3 Probe selection
Always use the short neck ear tips that are designated for Interacoustics OAE measurement. Use of the incorrect tip
could invalidate the OAE measurement.
In general, flanged or mushroom shaped ear tips will be used for most testing. The table below can be used
as a guide to help you select an appropriate ear tip size.
