The efferent auditory system is thought to play a role in the origin of tinnitus. Part of this system can be tested in humans with contralateral suppression of otoacoustic emissions. Stimulation of the medial olivocochlear efferent system is responsible for this reduction of otoacoustic emissions after contralateral acoustic stimulation. Previous research on patients with tinnitus showed inconclusive results. With wavelet analysis both time and frequency information of the emission can be analysed and compared. Contralateral suppression of otoacoustic emissions was therefore measured in tinnitus patients (n = 26) and normal subjects (n = 37) and analysed using wavelets. No significant difference in suppression was found between the tinnitus patients and the control group.
传出听觉系统被认为在耳鸣的起源中起作用。该系统的一部分可以通过对侧声发射抑制在人类中进行测试。对内侧橄榄耳蜗传出系统的刺激负责在对侧声刺激后减少声发射。先前对耳鸣患者的研究结果尚无定论。通过小波分析，可以分析和比较发射的时间和频率信息。因此，使用小波对耳鸣患者（n=26）和正常受试者（n=37）的声发射对侧抑制进行了测量和分析。在抑制方面，耳鸣患者和对照组之间没有发现显著差异。
