Accommodating for Noisy Recordings
In certain situations, it is possible that there may be noise or artifact in your ENG recordings that
the software may misinterpret and mark as beats of nystagmus.
Figure 1.26 Noise in ENG recording
To accommodate for this noise so that fewer nystagmus beats are incorrectly marked, you can go
into configuration for the specific test by double-clicking in the test window. Go to the Analysis tab
and increase the minimum amplitude of fast phase to 2 or 3 degrees.
