The acoustic middle ear muscle reflex thresholds towards white noise and fast sequences of clicks were determined in 46 normal-hearing young adults using electronic averaging. For white noise the thresholds were normally distributed around an average value of 72.7 dB SPL. With sequences of clicks the threshold depended above all on the click repetition rate within each stimulus sequence. When the repetition was 128/sec the threshold distribution was almost normal around an average value of 73.9 dB SPL. For the individual test subject there was good correlation between the white noise and the click reflex thresholds. It was our impression that the click generated reflexes had a more well defined threshold than with white noise stimuli, but this impression needs further validation.
使用电子平均法，测定了46名听力正常的年轻成年人对白噪声和快速点击序列的中耳肌声反射阈值。对于白噪声，阈值呈正态分布，平均值约为72.7 dB SPL。对于点击序列，阈值首先取决于每个刺激序列中的点击重复率。当重复率为128次/秒时，阈值分布几乎呈正态分布，平均值约为73.9 dB SPL。对于个体测试对象，白噪声和点击反射阈值之间存在良好的相关性。我们的印象是，点击产生的反射阈值比白噪声刺激的阈值更明确，但这一印象需要进一步验证。
