摘　　要：目的探讨采用卡尔曼加权平均(Kalman-weighted averaging,KWA)的听性脑干反应(ABR)测试中,受试者不同测试状态对残余噪声及ABR波V振幅的影响。方法选取21例(42耳)18~34岁听力正常成年人,分别在安静诊室内三种不同的状态下(安静平卧、坐位、写字)使用卡尔曼加权平均的新型ABR系统(vivosonic integrity system)进行ABR测试,同时使用传统ABR测试系统(interacoustics,IA)在隔声屏蔽室内进行ABR测试,记录各状态下受试者ABR反应的残余噪声水平和波V幅值并进行比较。结果①传统ABR和卡尔曼加权平均ABR三种不同测试状态(平卧、坐位、写字)下波V振幅没有显著差异(P>0.05);②卡尔曼加权平均ABR安静平卧和坐位两种状态下的残余噪声水平较传统ABR低,但无统计学差异(P>0.05);卡尔曼加权平均ABR在写字状态下的残余噪声水平显著高于其他三种状态(P<0.05);③写字状态下卡尔曼加权平均ABR的残余噪声、波V振幅在左右耳之间没有显著差异(P>0.05)。结论与传统ABR相比,卡尔曼加权平均ABR在写字状态下的残余噪声显著升高,但安静平卧和坐位状态下的残余噪声水平与传统ABR无显著差异,受试者的不同测试状态对残余噪声水平有一定影响。Objective To study the impact of a subject's testing state on residual noise level and ABR wave V amplitude during non-sedated ABR testing using Kalman-weighted averaging(KWA).Methods Twenty-one adults(18~34 years old,42 ears)with normal hearing were enrolled for non-sedated ABR testing under three different states(lying,sitting,and writing)in a quiet room using a new Kalman-weighted averaging ABR system(vivosonic integrity system).The residual noise level and the amplitude of wave V for click ABR(cABR)of each subject were recorded.The traditional ABR test system(interacoustics,IA)was also used to record ABR with the residual noise level and the amplitude of wave V measured at the same time.Results①There was no significant difference in amplitude of wave V between traditional ABR and non-sedated ABR in three different testing states(P>0.05).②The residual noise levels in the lying and sitting states of KWA ABR were lower than those of traditional ABR,but there was no statistically difference(P<0.05).The residual noise level of the KWA ABR system in writing state was significantly higher than that of the other three conditions(P<0.05).③There was no significant difference between the left and right ears in the residual noise level and amplitude of wave V for non-sedated ABR in writing state(P>0.05).Conclusion Compared with traditional ABR,the non-sedated KWA ABR system in uriting state was significantly higher than that of the other three conolitions.Hawever,the residual noise level in lying and sitting states had no significant difference with conditional ABR,and different states of the subject had impact on the residual noise level in the ABR testing to sone extent.
