The current stage of the development of the test methods of otoacoustic emission (OAE) in audiology is introduced.A probe was developed to be used with Hearing-evoked electric potential test instrument. The problems of the probe and how to resolve these problems are discussed. The probe developed by us are mainly used with bone-conduct earphone.The feeble otoacoustic emission signals,extracted from ear canal,are processed with certain technical methods,and interfaced with Hearing-evoked signals test system,...
