Abstract
Objective To compare the amplitudes and latencies of wave Ⅴ between chirp and click evoked auditory brainstem responses(ABR) and to discuss whether chirp is more advantageous in ABR test.Methods The chirp and click-evoked ABRs of 16 normal-hearing infants (24 ears) were recorded. The wave Ⅴ amplitudes at the stimulus intensities of 10-70 dB nHL and latencies at the high and threshold intensities were compared between chirp and click-evoked ABR.Results There was no significant difference in the wave Ⅴ amplitudes between chirp and click-evoked ABR at the intensities of 20-70 dB nHL. At the intensity of 10 dB nHL, the positive rate of wave Ⅴ elicited by chirp was significantly higher than that elicited by click. At the high stimulus intensity, there was no significant difference in the latencies of wave Ⅴ between chirp and click-evoked ABR, while at the threshold intensity, the latencies of wave Ⅴ elicited by chirp were significantly longer than those elicited by click.Conclusion The advantage of chirp is not obvious in increasing the amplitudes of wave Ⅴ as compared with click in ABR test, and the waveforms of wave Ⅰ and Ⅲ elicited by chirp are less typical than those elicited by click. Further studies are needed before the clinical application of chirp to ABR test.关键词
