Diagnostic reference data for the monaural brain-stem auditory evoked response (BAER).
The objective of the investigation was to establish 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; mean age = 20.33 years) and male (N = 30; mean age = 21.33 years) students aged between 18 and 25 years (mean 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 application and further research.
