Electrophysiologic assessment using the Auditory Brainstem Response (ABR)
The ABR is a key tool for estimating auditory thresholds in infants under six months and for individuals unable to perform behavioral hearing tests. It utilizes rapid-onset stimuli like clicks or chirps to assess the integrity of the auditory pathway, providing a basis for threshold investigation. In addition to clicks or chirps, more frequency-specific information is needed to estimate thresholds across the frequency range. In addition, both air and bone conduction testing are necessary. This information is required to begin habilitation when an impairment exists. Tips on conducting these tests and suggestions for test sequence are discussed.
