摘　　要：Transient Evoked Otoacoustic Emission(TEOAE) has been widely researched and applied in auditory field during these years.Correctly indentifying TEOAE is the basis of study and application.Aiming at the limitations of the traditional TEOAE identification methods,this study put forward a new discrimination criterion between TEOAE and residual stimulus artifact in time frequency domain according to their different features.This method has been demonstrated to improve the correctness of identification,and will help the accurate diagnosis of cochlear function.Transient Evoked Otoacoustic Emission(TEOAE) has been widely researched and applied in auditory field during these years.Correctly indentifying TEOAE is the basis of study and application.Aiming at the limitations of the traditional TEOAE identification methods,this study put forward a new discrimination criterion between TEOAE and residual stimulus artifact in time frequency domain according to their different features.This method has been demonstrated to improve the correctness of identification,and will help the accurate diagnosis of cochlear function.
