Abstract:
Objective To study the characteristics of auditory brainstem response by chirp and click stimuli in normal hearing children.Methods A total of 97 children (194 ears)with normal hearing were recruited,including 50 male (100 ears),and 47 female (94 ears).The CE-chirp and the click acoustic stimulation were used to,and the ABR waveforms and latencies were obtained.ResuIts The chirp-ABR Ⅰ wave recognition rate (36%)was significantly lower than that of click-ABR (100%).At 80 dB nHL,chirp-ABR V wave latency was shorter than click-ABR,the difference was statistically significant (P< 0.05 ).The chirp and click ABR V wave response thresholds showed no significant difference (P>0.05).At 80 dB nHL,no statistical significance of two kinds of a-coustic stimulation of ABR V wave amplitude difference (P>0.05).At 50 dB nHL,chirp-ABR significantly in-creased than click-ABR V wave amplitude with statistically significant differences (P<0.05).At 80,and 50 dB nHL,chirp-ABR showed no differences in the amplitude of V wave (P>0.05 ).ConcIusion The chirp acoustic stimulation produced the larger response amplitude,and was faster,demonstrating the noticeable advantages to tes-ting children.
