Methods: This case control experimental study was conducted on 60 children out of them 30 were apparently healthy and 30 having developmental delayed. Database was collected after assessing threshold level in both the subjects. Brainstem Evoked Response Audiometry (BERA) was used as a tool for assessment of hearing loss. Results: Results showed that there was a significant difference between developmental delayed subjects and normal healthy subjects. The thresholds obtained by developmental delayed subjects’ presentation were lower than that by normal subjects. Conclusion: Overall it was concluded that, interpeak latencies were prolong in the subjects having delayed milestone as compare with normal healthy infants. The study promotes the use of delayed milestone activity shows sensory neural hearing loss presentation by neurophysiologists as it not only saves valuable clinical time but also improves the diagnostic accuracy for delayed milestone activity in infants.
