Viewing DPOAE Test Details or Retesting an Ear with a Refer
Result Immediately After a Test

This flow chart begins at the point immediately after the DPOAE test has been successfully
completed and the SEE DETAILS message is displayed.















The PASS/REFER indicator displayed in the first SEE DETAIL box is for the overall test. The
PASS/REFER indicator in the second X KHZ DP ## box is for the individual frequency being
displayed. The displayed PASS/REFER indicator is based on research published by Gorga,
Neely, Ohlrich, Hoover, Redner and Peters (1997)

. For more information about the criteria

needed for a PASS or REFER indicator to appear, see Chapter 12 System Default Protocol.

In the X KHZ DP ## message box, the number after the DP abbreviation is the amplitude of the
distortion product emission. In the second line, the number following the word NOISE is the
amplitude of the noise floor. Remember that RESTART will return to the PERFORM DPOAE
message at any time.

When a Refer result has occurred, selection of the DOWN arrow key from the SEE DETAILS
message will display a REFER RESULT RETEST message. Selection of the DX SELECT button
will then initiate another test and increment to the next test ID number so that all tests performed
in this way will be present in memory, until the tests begin to be overwritten once the capacity of
the memory is achieved.
