Freq range
The frequency range tested may be selected with the left and right arrow
keys.
1.5-8k tests at six F2 frequencies: 1.5, 2, 3, 4, 6 and 8kHz
1-6k tests at six F2 frequencies: 1, 1.5, 2, 3, 4 and 6kHz
2-6k tests at four F2 frequencies: 2, 3, 4 and 6kHz
The frequency range for DP 12 Freq is xed at 1-8kHz.
Start
With start mode set to On (default), the testing will proceed from Checkt
to Test as soon as the Otoport detects a stable probe t, without the need
for the user to select Start.
With the Start setting O󰀨, the user must initiate the test by selecting Start
when the probe t and test conditions are satisfactory.
Irrespective of the Start setting, the Start button is available in order that
the user can initiate a test.
Stop
The Stop setting controls whether the test automatically stops when the
pass criteria are met. If Stop is turned O󰀨, the test will run for longer, but
the OAE levels will be more accurately measured. If Stop is On when
screening, the test will be as short as possible.
Band SNR
Band SNR sets the minimum Signal to Noise Ratio required in each band
before that band passes. The SNR calculated is dependent on the noise
mode used (see 15.2.1 Noise mode). By default, it is set to 6dB SNR.
