Viewing DPOAE results with normative data

When testing is complete, the green 'READY' light is illuminated
and a display similar to Main Menu will appear. This screen again
indicates the test ear and also gives the results of the test.
•
'PASS' on the screen indicates that the patient passed the
screening
•
'REFER' indicates that the patient did not pass the
screening
•
'NOISY' indicates that excessive noise was present during
the test
•
'NO SEAL indicates that a seal was not maintained
throughout the test
•
'FIT ERR' indicates inadequate probe placement in the
ear canal to produce target stimulus intensities
When the test result is 'NOISY', 'NO SEAL', or 'FIT ERR' the
tester should reposition the probe, selecting a different size ear tip
if necessary, and retest.
If the test result is 'REFER' the tester can determine from the
printout whether the test should be repeated.
To review the results, push the
the graph. After reviewing the results, again push the
arrow key to return to the Results display or the
return to the Main Menu.
Once the review screen is exited, results are no longer viewable
within the device. Printing or transferring to the PC is required for
continued viewing options.

The OtoRead will display the Expanded Boys Town Norms
template for eligible DPOAE test results. The norms template has
no effect on the overall test results and is for display purposes
only. The values used to create the template are shown in Table
A1 from Gorga, M.P., Neely, S.T., Ohlrich, B., Hoover, B., Redner,
J. and Peters, J. (1997). "From laboratory to clinic: a large scale
study of distortion product otoacoustic emissions in ears with
normal hearing and ears with hearing loss." Ear & Hearing, 18,
440-455. The template may be used as a guide when evaluating
DPOAE test results. The light shaded area at the top of the
template represents the 90th to 95th percentile of DP amplitudes
from the hearing impaired population. DP amplitudes within or
above this range indicate a high probability of normal hearing. The
light shaded area at the bottom of the template represents the 5th
to 10th percentile of DP amplitudes from the normal hearing
population. DP amplitudes within or below this range indicate a
high probability of hearing loss. The dark shaded area in between
represents a range of uncertainty where the normal hearing and
hearing impaired populations overlap.
