Abstract

The objective of the investigation was to established diagnostic reference data for the normal BAER. BAERs were elicited from the target (R) ear using clicks presented at 70dBnHL. Relevant latency and amplitude data were obtained from 60 selected normal hearing Indian undergraduate females (N=30; X age = 20.33 years) students aged between 18 and 25 years (X age = 20.73 Years). Diagnostic reference data were established for the absolute latencies of peaks I to VI; relative latencies of peaks I-III; III-V and I-V; absolute amplitudes of peaks I and V and the relative amplitude ratio of peaks V:I. These results are discussed in terms of the literature and implications for clinical applications and further research.
