| Label(2)
| | SetSubAveNum(16)
| This sets the number of averages per frequency to 16. NOTE THAT YOU HAVE TO STOP the sampling program, when a adequate response (according to your criteria) has been obtained. It usually takes about 32 averages to get a nice S/N ratio above 10-15 dB from well-babies. | SetEMSon
| | SetOverSamplingOn
| | SetMaxNoiseRej(8)
| | SetAutoRejOn
| | DisableQuickSaveButton
| | LoadProbeFile(childdef.prb)
| | | SetDataDirectory(C:\data\dpoae) | Directory where the data are saved. CHANGE accordingly. | Protocol5(2,128,90,10)
| | RestartCondition(1,0,5,1,1)
| | SetCustomFreqCount(5)
| This variable defines the number of tested frequencies. For example IF you want to test 10 frequencies you should place 10 in the place of 5 | SetCustomFreq(1,1500)
| This is the frequency of the FIRST testing point. REMEMBER you should specify as many testing frequencies as the number of point defined in the previous command. | SetCustomFreq(2,2000)
| | SetCustomFreq(3,3300)
| The frequency has been set to 3300 Hz and NOT 3000 in order to compensate for the DP-GRAM notches caused by the interaction of the cubic distortion products and the stationary waves at the external meatus. | SetCustomFreq(4,4000)
| | | SetCustomFreq(5,5000) | | | SetFRatio(1.22) | Change this ratio to 1.18 if you would like to record responses from pre-term infants | | SetTestParameters(1.22,75,65) | | | DPgram(0,75,65) | This sets the stimulus intensity to 75-65. Change accordingly BUT remember to change the stimulus intensity in the previous command. | | ProbeCheckFitOn | Activation of the probe-fit procedure , prior to data sampling | | GetPatientData | This activates the patient-SAVE menu of the ILO software | DataFileSave
