Abstract
Auditory brainstem responses (ABR) were recorded in 36 normal adult ears.
1. The standard deviations of latency of each response were found to be less than 0.20 msec at click intensity of 75 db SL.
2. The shapes of the wave IV-V complex were classified into 5 different patterns, but the variations in the shapes of the wave IV-V complex were not clinically significant.
3. The intertest differences of the wave V latency were found to be less than 0.10 msec in 32 ears of 35 ones(91%). Those of wave I-V interval were less than 0.10 msec in 31 ears of 35 ones (88%).
4. It should be abnormal, when the interaural difference of the wave V was more than 0.4 msec or when that of wave I-V interval more than 0.45 msec.
