Brainstem-evoked response audiometry: normative data from the preterm infant.
Brainstem-evoked response audiometry (BERA) was performed on 40 preterm infants who had low neonatal risk scores. Mean latencies for waves I and V were obtained from four age-groups, 33-34, 35-36, 37-38 and 39-40 weeks conceptional age. The results indicate that BERA is a valuable and reliable tool in assessment of auditory function in the preterm infant. Also for classification of abnormality it is recommended that 2 standard deviations from the mean latency of wave V be used.
