正常成年人水平特异性CE-Chirp刺激声与Click刺激声诱发听性脑干反应的比较
Comparison of ABRs Induced by Level Specific CE-Chirps and Clicks in Normal Adults
摘要
Abstract
Objective To report ABR responses induced by level specific CE-chirps(LS CE-chirps)and Clicks in normal adults and the relationship between their thresholds and pure tone thresholds for their potential values in objec-tive evaluation of auditory function.Methods Air conduction pure tone thresholds at 0.5,1.0,2.0 and 4.0 kHz were ob-tained in 21 normal adults(42 ears).wave V amplitudes in response to LS CE-chirps and clicks at 80,60 and 40 dB nHL were measured,as well as wave V thresholds and latencies of waves I,III and V at 80 dB nHL.Latencies and am-plitudes of ABRs induced by the two kinds of stimuli,as well as the relationship between wave V thresholds and pure tone thresholds,were compared.Results At 80,60 and 40 dB nHL,wave V amplitudes in LS CE-Chirp induced ABRs were greater than those in click induced ABRs(P<0.001).The difference between Wave V threshold and average pure tone threshold is smaller for LS CE-Chirp induced ABRs than click induced ABRs(P<0.05).At 80 dB nHL,wave I la-tency was longer in LS CE-Chirp ABRs than in click ABRs(P<0.001),but not for waves III and V latencies(P>0.05).Conclusion Compared with click ABRs,the amplitudes of LS CE-Chirp ABRs are greater in response to high and low intensity stimuli,with the wave V threshold closer to pure tone thresholds,which should be more conducive to inferring pure tone thresholds,but individual variabilities in latency are noticeable.关键词
