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.
