查询词典 steady state

Objective To explore the prediction of bone-conduction of audiometric threshold in normal-hearing adults using multiple auditory steady-state response. Methods BC-ASSR and BC-A were recorded in 20 normal-hearing adults(10 males and 10 females). The response thresholds and the behavioral thresholds were compared at 0.5, 1.0, 2.0 and 4.0kHz to get the correlation and regression formulae.

目的 探讨多频听性稳态反应评估听力正常青年人骨导纯音听阈的可能性，旨在观察听力正常青年人骨导多频听觉稳态反应测试的正常值特点，进一步探讨骨导ASSR的反应阈与骨导纯音听阈的相关性，为临床上对不能配合做纯音测听的患者行听力评估时提供客观参考。
