Auditory brain stem responses from graduates of an intensive care nursery using an insert earphone.
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.
