多频听性稳态反应评估听力正常青年人纯音听阈的探讨

Prediction of Pure Tone Audiometry Threshold in Normal-hearing Adults Using Multiple Auditory Steady State Response

目的 探讨多频听性稳态反应(multipleauditorysteadystateresponse ,MASSR)评估听力正常青年人纯音听阈的可靠性。方法 对2 8名( 5 6耳)听力正常青年人进行MASSR及纯音听阈检查,记录0 .5、1、2、4kHz反应阈及行为听阈,比较二者间的相关性。结果 MASSR反应阈左右耳间无显著性差异;各频率间MASSR反应阈比较,0 .5kHz较其他各频率有显著性差异(P <0 .0 0 1) ,1、2、4kHz三个频率间均无显著性差异(P >0 .0 5 )。MASSR反应阈与纯音听阈在0 .5、1、2、4kHz相关系数分别为0 .71、0 .83、0 .86、0 .87。结论 MASSR反应阈与纯音听阈间有较好的相关性。

Objective To explore the prediction of pure tone audiometry(PTA) threshold in normal-hearing adults using multiple auditory steady state response(MASSR).Methods MASSR?PTA were performed to 28 normal hearing adults(56ears).The response thresholds and the behavioral thresholds were compared at 0.5?1?2?4 kHz to get the correlation factors and regression formulate.Results There were no significant differences between the right ear and the left ear for the response thresholds. There was significant difference at 0.5 kHz for MASSR.At other three frequencies, no siginificant differences were found.Pearson correlations between the response thresholds and the behavioral thresholds were 0.71?0.83?0.86?0.87 at 0.5, 1, 2, and 4 kHz.Conclusion MASSR can be used to predict the pure tone audiogram. The study illustrates that the correlation between the response thresholds of MASSR and PTA thresholds is strong.
