About the ABRIS module

The Eclipse ABRIS is intended for use in the audiologic evaluation and documentation of ear and nerve dis-
orders using auditory evoked potentials from the inner ear, the auditory nerve and the brainstem. The target
population for Eclipse ABRIS is newborns.
ABRIS is used for objective hearing assessment of new-borns. ABRIS is used for hearing screening and for
this purpose broad band stimuli are applied. These may, for example, consist of repeated clicks, chirps and
noise bursts or of amplitude and/or frequency modulated noise. The test will check for brainstem activity in
response to click stimuli at a fixed level, and create an automated auditory brainstem response (AABR). The
ABRIS recording will stop if a pass criterion is met, otherwise it will use the full recording time (120sec) and
report Refer.
ABRIS is based on steady state techniques, and can only use a click stimulus at the intensity 30, 35 or 40dB
nHL, one ear at a time. The data acquisition of the ABRIS recordings takes place from the surface electrodes
positioned at specific recording points on the patient.
The ABRIS software computes a conclusion "Refer" (false or true positive) or "Pass" (false or true negative).
All ABRIS statistics and the recordings are stored on the Laptop / Desktop computer for later examination
and diagnosis.
