Above is the TEOAE protocol editing window.
Protocol Name: the text entered into the Protocol Name field is what will appear in the instrument when
the protocol is loaded. This should be kept to approximately 14-16 characters in length so that the full
protocol name can be viewed on the instrument display.
Target Peak Pressure: sets the target intensity for the click stimulus. Target peak pressure is adjustable
between 70 and 85 dB SPL.
Averaging Time: the maximum length of time the TEOAE measurement will run before displaying a Pass
or Refer result. The test will stop automatically once a Pass result is obtained. The averaging time can
be adjusted between 8 and 64 seconds.
Evaluation Criteria: check the box if a Pass or Refer outcome should be determined for this protocol.
Indicate the number of passing frequencies required for the overall test result to be
Pass.
Number of
passing frequency bands for a test pass can be set to any value between 1 and 10, but cannot exceed
the total number of frequency bands tested.
SNR to Pass: defines the minimum SNR required for that frequency to be considered a passing frequency
band. SNR to Pass is adjustable between 3 and 10 dB
Minimum TE: defines the minimum TEOAE (signal) amplitude required for that frequency band to be
considered a passing frequency. Minimum DP is adjustable between -20 and 0 dB SPL. If the user does
not wish to use minimum amplitude as part of the Pass criterion, n/a can be selected for this parameter
and/or the instrument setting for
Use Minimums
can be set to
