TEOAE test config
Field Description
TE mode name User settable mode name
Range: 8 characters max
Stim level Peak target stimulus level for testing
Range: 70-90 dB pe
Stim range Stimulus OK range – the permitted change in stimulus level during
TEOAE testing before probe movement warnings are provided.
If the stimulus is out of range, the Stimulus OK indicator will
extinguish and the screen will display ‘Check probe fit’.
Range: +/- 1, 2 or 3dB
Noise reject The threshold of noise permitted during a test above which causes
data to be rejected from the final result. Reducing the noise reject
level could result in better quality data collected, but less data will
be accepted if there is noise, which could result in a longer test
time. Increasing the noise reject level will allow more data to be
collected in noisy conditions. This could have a negative affect
on data quality as it could contain more noise and there is an
increased risk of noise artefacts.
Range: 40-74 dB SPL
Ring alert Controls the sensitivity of a warning provided if the stimulus
becomes oscillatory and rings. Stimulus ring only occurs in large
ear canals, so is not an issue when making OAE measurements
on newborns. A ringing stimulus can increase the risk of a
stimulus artefact. The Otoport displays ‘Ringing’ during checkfit, to
warn the users if the stimulus is ringing (see fig. 1). In most ears,
the stimulus click becomes ‘flat’ following the click stim (see fig. 2),
but in longer large ear canals the stimulus can oscillate for longer.
The Ring alert displays the ratio in dB of the peak stimulus over
the stimulus level recorded at 3 milliseconds.
Range:-10 to -30dB
