Abstract
Introduction- Hearing loss and deafness are global issues that affect at least 278 million people worldwide. Two-thirds of these people live in
developing countries. Cross sectional, comparative study, 20 normal and 20 DR children w Method- ere selected. Parameters for interpretation
were Hearing threshold in decibles(dB) of each ear seperately and Interpeak latencies. All the parameters were compared at 80 dB stimulus
intensity level. 35% cases had a hearing threshold of 90 dB. 20% cases ha Result - d a hearing threshold of 80dB and ≥100dB. 25% of
the subjects had a hearing threshold of 70dB. Interpeak latencies in Right & Left ear namely I-V, III-V and I - III inter-peak latency values were
signicantly prolonged in the developmental delayed children group. Interpeak latenc Conclusion- ies are prolonged in the children having
developmental retardation as compared with normal children
