Abstract:
Auditory brainstem response (ABR) peak measures were compared for a custom ear canal electrode and traditional mastoid and ear lobe reference electrode sites with the assumption that the ear canal electrode would yield larger Wave I amplitudes. In this study, Waves I, III, and V latencies and amplitudes were measured and compared in twenty participants between the ages of 18 and 50, with particular interest in a potential Wave I advantage using the custom ear canal reference electrode. The statistical analysis suggested that all reference electrode sites yielded comparable results with no statistical differences in peak latency or peak-to-trough amplitude for Waves I, III, and V. Although the custom ear canal electrode did not produce larger Wave I amplitudes over the other two references, a deeper placement of the ear canal electrode might have yielded different results.
