title: Auditory brain stem responses from graduates of an intensive care nursery using an insert earphone.
abstract: Auditory brain stem responses (ABR) were measured from graduates of an intensive care nursery using an insert earphone. Approximately 95% of all ears had click-evoked ABR thresholds of 30 dB nHL or less. Absolute latencies of waves I and V were within the range observed for a circumaural earphone, once the delay introduced by the insert earphone's sound delivery tube was taken into account. Finally, interpeak latency differences and interaural symmetry were comparable to values observed when a similar group of patients were tested with a circumaural earphone.
