Brainstem wave V latencies to tone pip stimuli.

The present study was undertaken to examine the feasibility of using tone pip stimuli rather than conventional clicks in brainstem evoked response (BER) audiometry. Trains of 2000-Hz tone pips, 4000-HZ tone pips or clicks were presented at seven intensity levels to six normal young adults. Results demonstrated that BERs can be readily elicited by tone pips. This latter finding may be attributable to the differences in stimulus rise times. Tone pips appear to introduce greater frequency specificity to BER audiometry without a marked loss in the ability to elicit the response.
