ABSTRACT Introduction: Hearing impairment have an important consequence for language acquisition, communication, cognitive, social& emotional development; Perceived maternal stress is a risk factor for hearing impairment in infants upto 12 months of age. BERA being a noninvasive, objective test when used and interpreted properly provide a useful method of obtaining reliable estimate of hearing sensitivity among the infants. Aims: 1) Screening for Auditory Impairment in infants upto 12 months of age who are at risk.2) Assessment of perceived stress on mother. Materials and method: The present study was an Analytical, Observational study. This study was conducted for a period of 12 months at R. G. Kar Medical College and Hospital, Kolkata. Total 85 subjects were included in this study. Result: Our study showed that, more number of patients had A+ blood group [37 (43.5%)] but this was not statistically significant (p.1556). (Z=1.4204). Conclusion: We concluded that Perceived stress scale was positively correlated with BERA wave changes in infants attending neurophysiology laboratory at R.G. Kar medical college which is a tertiary care centre.
