The present paper resumes the results obtained from measurement of spontaneous otoacoustic emissions (SOAEs), in terms of rate of occurrence, frequency spectrum and intra- and intersubjective variability in 104 normal ears (52 subjects). SOAEs have been detected in 27 ears (26.0%) and in 16 subjects (30.8%); bilateral SOAEs have been observed in 11 subjects (68.8%). Frequencies of the strongest emissions ranged from 1 to 2 kHz (96.3%); amplitudes varied from 3 to 20 dB SPL above the background noise. Spectra were always very sharp and stable in frequency, less in amplitude. Present results agree well with the data available in literature.
本文总结了对104只正常耳朵（52名受试者）的自发性耳声发射（SOAE）进行测量所获得的结果，包括发生率、频谱以及个体内和个体间的变异性。在27只耳朵（26.0%）和16名受试者（30.8%）中检测到了SOAE；在11名受试者（68.8%）中观察到了双侧SOAE。最强发射的频率范围为1至2kHz（96.3%）；幅度在背景噪声之上从3至20dB SPL不等。频谱在频率上总是非常尖锐且稳定，在幅度上则不然。目前的结果与文献中的现有数据非常吻合。
