刺激频率耳声发射的研究进展

Research development of stimulus-frequency otoacoustic emission

为了推动对刺激频率耳声发射(SFOAEs)的产生机制和检测方法的深入研究并推动SFOAEs的临床应用,综述了刺激频率耳声发射的研究进展,包括SFOAEs的产生机制、SFOAEs的检测方法、SFOAEs的检测评估与听力损失的关系、SFOAEs对听觉系统频率选择特性的评估潜力。在SFOAEs的产生机制的介绍中,分别从SFOAEs的产生源、SFOAEs的传输通路、SFOAEs信号的成分特征等几方面进行了论述。在SFOAEs的检测方法中,重点介绍了经常涉及到的双音抑制、非线性压缩、频谱平滑和扫频音等方法。最后,对SFOAEs的临床应用进行了展望。

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.
