Auditory evoked potentials (AEPs) are very small electrical voltage potentials signal generated by a sound through the auditory pathway. Age and gender influence on the BAEPs deserve keen appraisal for correct clinical application and inference. Objective: To get normal range of latencies and amplitude of waveforms of BAEP in healthy normal persons in various age groups. Methods: BAEPs from either ear of normal hearing 150 men and 145 women in 1 year to 73 year age range were studied. Absolute

Result: In male, wave I value was significantly higher in ≥ 45 years age group than 1-14, 15-24 and 25-34 years age groups. In female, wave I is significantly higher in 35-44 and ≥ 45 years age groups. i.e at extreme of age group >45 yrs, it was 1.77±0.18. The latency of wave II was significantly higher in 35-44 and ≥ 45 years age groups in male i.e 2.74±0.17, 2.78±0.17 respectively. In female, wave II significantly higher in 35-44 and ≥ 45 years age groups i.e 2.70±0.18. 2.80±0.15 respectively. There were significant higher latencies of wave III in 35-44 and ≥ 45 years age groups in male i.e 3.81±0.15, 3.86±0.12 respectively. There was no significant difference found for wave IV in different age groups in male. The latency of wave IV was significantly higher in ≥ 45 years age group compared to 25-34 years age group in female i.e at extreme of age group >45 yrs, it was 4.84±0.20. There was no significant difference found for wave V in different age groups in male and female respectively. Conclusion: Significant changes in the BAEPs in our study support the possible role of age and gender as contributively factors for normal variations.
