This study sought to clarify the clinical relevance of spontaneous otoacoustic emissions (SOAEs) and to define the hearing loss level (and frequency) at which absence of SOAE is found. Findings from 126 ears of patients with sensori-neural hearing loss showed an incidence of SOAEs in 18.25% of the cases (23 out of 126 ears). SOAEs were never found when hearing loss at 1,000 Hz exceeded 10 dB. The presence of SOAE seems to indicate a good cochlear functioning at least in the mid-frequencies. Although the incidence of SOAEs is markedly lower than that of evoked otoacoustic emissions (EOAEs), SOAE recording is shown to be a good test, rapid, non-invasive for audiological screening, the presence of SOAE confirming a hearing threshold of less than 10 dB at 1,000 Hz, the absence of SOAE being inconclusive.
本研究旨在阐明自发性耳声发射（SOAE）的临床相关性，并确定发现无SOAE时的听力损失水平（及频率）。对126例感音神经性听力损失患者的耳部研究结果显示，SOAE发生率为18.25%（126耳中有23耳）。当1000Hz处听力损失超过10dB时，从未发现SOAE。SOAE的存在似乎表明至少在中频区域耳蜗功能良好。尽管SOAE的发生率明显低于诱发耳声发射（EOAE），但SOAE记录被证明是一种很好的测试方法，快速、无创，可用于听力筛查，SOAE的存在证实1000Hz处听力阈值低于10dB，而无SOAE则不能得出确定性结论。
