9. Obtained records Dropdown box to view previous test results of the current session.
10. Rejection bar During recordings the operator can change the rejection criteria manually by clicking on
the slide bar and moving it to the left to decrease or to the right to increase the rejection criteria.
Set a lower rejection level to avoid recordings of impulsive noises like speech, traffic, fans etc., move the
slide bar to the left. To allow more ambient noise without rejection of OAE data, by moving the slide bar to
the right. The rejection should be set as low as practically possible. To turn off rejection, move the slide
bar to the outermost right to disable the rejection.
The default rejection criteria can be set in the system setup.
Rejection indicator Indicates whether the measured data passes the rejection criteria.
When the rejection indicator is green only, data is being measured.
If the rejection indicator becomes red to the right side of the criteria handle, like shown in the figure
above, data are being rejected.
 If rejection occurs, reduce patient noise (e.g. crying) or reduce the ambient noise. Check also that
probe insertion is correct.
 If needed, move the rejection handle towards the right to allow more acoustical noise.
The Rejection Level slider allows setting the rejection level limit between -30 and +30dB SPL. Sweeps
recorded above the set rejection level are considered to be too noisy and are rejected.
Artifact rejection is dependent upon the Rejection Level and the Tolerance level set in the protocol. If
the Tolerance Level is exceeded, the pop-up below is displayed.
