7.4. Testing in the Default Modes

For either DPOAEs or TEOAEs there are a default test protocol and a user
definable protocol called a "custom"setting. The default protocols will be used
unless a custom protocol is selected by the user. See
Settings - Test Mode
and the Advanced Options for DPOAE Testing or TEOAEs allow the user to
change test protocols.
The settings for testing in the default DP protocol are as follows:
Number of Frequencies Tested = 4 Averaging Time = 4 Seconds
Frequency Range = 2 kHz to 5 kHz Pass SNR (Signal-to-Noise Ratio) = 6 dB
P1 (Intensity of F1 in dB SPL) = 65
Test Pass = 3
P2 (Intensity of F2 in dB SPL) = 55
The settings for testing in the default TE protocol are as follows:
Number of Bands Reported = 6
