Abstract:In order to promote the profound study of the generation mechanism and detection methods of stimulation frequency otoacoustic emissions (SFOAEs) and push forward the clinical application of SFOAEs, the research development of stimulusfrequency otoacoustic emissions (SFOAEs) is reviewed in this paper, which includes SFOAEs generation mechanism, SFOAEs detection methods, the relationship of SFOAEs detection and assessment with hearing loss, and the evaluation potential of SFOAEs to the frequency selectivity of the auditory system. The generation source, transmission pathway and the component characteristics of SFOAE signals are discussed in the introduction section of SFOAEs generation mechanism. In the SFOAEs detection methods the commonly involved twotone suppression, nonlinear compression, spectrum smoothing and swepttone methods are introduced emphasisly. Finally, the clinical application of SFOAEs is prospected at the end of this paper.
