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.
Abstract
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.Results ① There was no significant difference in am-plitude 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).③ There 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.Haw ever,the residual noise level in lying and sit-ting 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.
