Background: The central nervous system is no exception to the effects of aging. Physiologic changes due to aging have been suggested to impair the neurotransmission in the auditory pathways. Brainstem auditory evoked potential (BAEP) allows for the evaluation of such age-related transmission delays within the auditory system. Aims and Objectives: The present study, hence, intended to study healthy older subjects to attain a BAEP data normalized for age and gender for this less routinely studied age group. Materials and Methods: BAEP was recorded in 80 healthy normoacusic subjects (40 males and 40 females) in the age group of 41-80 years. BAEP latencies were compared in different age groups by oneway ANOVA. Correlations of latencies with age were performed using Pearson correlation coefficient. Gender differences in the older subjects were studied by unpaired t-test. P
