An auditory steady-state response (ASSR) is an electrophysiological response that is evoked by a periodically repeated (rapid) auditory stimulus.
An ASSR typically uses frequency specific stimuli (0.5, 1, 2, 4 kHz) with the goal of creating an estimated audiogram. In other words, it is a test used for performing a threshold assessment.
The Auditory Brainstem Response is an Evoked Potential that originates at the auditory nerve (Cranial Nerve VIII).
This test is used to assess the auditory system’s function from the cochlea through the brainstem.
This quick guide outlines the procedure for creating a pass/refer ABRIS test protocol. Parameters and settings should be based on an appropriate pass/refer criterion.
