Abstract

Auditory brain stem responses (ABRs) were measured for stimuli presented both by air conduction and by bone conduction. Stimuli included clicks and tone bursts at octave frequencies from 250 to 4000 Hz. ABR thresholds were comparable for air-and boneconducted stimuli. Wave V latencies were longer for boneconducted stimuli compared to similar responses for air conduction. This effect was evident for both clicks and tone bursts. The fact that these latency differences were largely independent of stimulus spectrum suggests that they are not due to differences between the frequency responses of air and bone conduction transducers. This finding is expected when one considers the interaction between output, threshold, and frequency for both transducer types. These data also supgest that there are inherent differences in transmission by air and bone conduction that affect response latency but are unrelated to the amplitude spectrum in the signal.
