Abstract

This study investigated the effects of homophasic and antiphasic stimulation on the binaurally evoked auditory brain‐stem responses (ABRs). Ten normal subjects were presented with two in‐phase (binaural condensation and binaural rarefaction) and two out‐of‐phase (left ear condensation, right ear rarefaction and right ear condensation, left ear rarefaction) stimulus configurations. The stimuli were 100‐μs clicks delivered at 47 dB SL (repetition rate 5.6/s). The ABRs were picked up between high forehead (active) and left earlobe (reference), the nasion served as ground. The earlier of the latencies obtained with homophasic stimulation was compared with the earlier of the latencies obtained with antiphasic stimulation. A subject‐by‐treatment analyses on the peaks (P) and troughs (N) of each component revealed significantly earlier latencies for the antiphasic condition for components IIN (p < 0.05), IIIP (p < 0.025), VIP (p < 0.01) and VIN (p < 0.025). Similar trends were apparent in components IVP (p < 0.1), IVN (p < 0.2), and VP (p < 0.1). No differences were observed for components IP, IN, IIP, and VN.
