Tinnitus in one female subject was found to be related to numerous (as many as 21) bilateral spontaneous otoacoustic emissions. The association of tinnitus and spontaneous otoacoustic emissions was empirically supported by the masking/suppression demonstration. The subject reported that her tinnitus occurred primarily in her right ear, which had linked, quasi-stable spontaneous otoacoustic emissions not found contralaterally. During one menstrual cycle, a pure tone was adjusted to match the predominant tinnitus pitch. The frequency of the tone generally followed the day-to-day shifts in the frequency of the associated spontaneous otoacoustic emission. The frequencies of these tones were a local minimum near the onset of menstruation, reaching a local maximum after menstruation.
在一名女性受试者中，发现耳鸣与大量（多达21个）双侧自发性耳声发射有关。耳鸣与自发性耳声发射之间的关联通过掩蔽/抑制实验得到了实证支持。该受试者报告称，她的耳鸣主要发生在右耳，而右耳有相关的、对侧未发现的准稳定自发性耳声发射。在一个月经周期内，调整纯音以匹配主要的耳鸣音调。该音调的频率通常跟随相关自发性耳声发射频率的每日变化。这些音调的频率在月经开始时接近局部最小值，在月经后达到局部最大值。
