This study includes eight normal, not at-risk for deafness, neonates and infants of age ranging from 2 days to 1 year. BERA was done at 2 kHz. frequency at 80 dB intensity. In the majority of the subjects, only wave I, II, III and V could be definitely identified. It was observed that latencies of waves decreased as age of neonate/infant increased. Decrease of latency was more marked in first 6 months of life (wave V from 7.2 ms to 6. / ms) as compared to next six months (wave V from 6. 1 ms to 5.9 ms). This could be because of rapid myelination in the first six months of life.
