2.3 Advanced configurations
relation between the two buffers, the stability of the re-
sponse and the presence of an OAE signal. Thus, the
settings for the minimum SNR value and the number of
frequencies for validation are disabled. Protocol
changes should only be performed by qualified person-
nel
Statistical detection
Enable the statistical detection (Method used in the previous version).
Min SNR
Minimum value (in dB) of the signal level compared to the noise level to consider the
OAE present (detected) at each frequency
Freqs Nb for PASS
The minimum number of frequencies with OAE present (detected) required to determine
"PASS" in screening mode
Max Test Time
Maximum test duration for each frequency in "screening mode" in case of no response
Power (Screening)
The intensity in dB in "screening mode" if "Protected access to settings" is activated.
Otherwise, the intensity is adjusted directly in the test window

Configuration of the click stimulus
You can configure the click stimulation correction. (This configuration is valid for ABR
, ECochG
and
VEMP
).
In the device main menu, click on "
Config
". The param-
eter adjustment window opens.
Click on "
Config Click
" to gain access to the advanced
click settings.
For acoustic and physiological reasons, the frequency reliability of the TEOAE test is between 2Khz and
4KHz, the validation criteria with a minimum number of frequencies above 3 can make the test slow and
prone to false negatives.
