Each test can be reviewed individually in the
QA Real Ear Test History
area.
Some adult ears with no significant hearing loss produce little or no OAE. If
possible, the Real Ear Test should be performed on an ear which is known
to have strong OAEs. Ideally, the same ear will be consistently used for the
tests so that changes in response can be easily seen, which may indicate a
change in the Otoport performance.
If a
Real Ear OK
result cannot be achieved in an ear which is known to
have OAEs, then:
• Check that the subject has no middle or outer ear problems, such as a
cold or wax blockage, which might prevent OAE recording.
• Check that a good probe fit has been achieved.
• Check that the probe coupler tubes are not blocked.
• Check that the probe still passes the probe calibration test (see above).
• Try recording emissions from another subject.
If a
Real Ear OK
result still cannot be achieved and if the resources are
available, a recording should be performed with a different probe or with
a different Otoport to help identify the problem. If the problem persists,
contact your dealer or Otodynamics.
