Click interaural attenuation (IA) was measured behaviorally and with the auditory brain stem response (ABR) in two unilaterally deaf adults with Etymotic ER-3A insert earphones, and TDH-39P and TDH-49P supraaural earphones. Stimulus crossover for each set of earphones was also determined with pure-tone audiometry. Pure-tone results agreed with previous research, showing that the ER-3A provided substantially greater IA than the supraaural earphones, particularly for low frequencies. For click stimuli, behavioral and ABR results revealed only modest, if any, improvement in IA with the ER-3A relative to the supraaural earphones. The results of this study suggest that while the ER-3A earphones provide a clear IA advantage for behavioral pure-tone audiometry, they do not eliminate the need for contralateral masking of click stimuli in ABR testing.
