The latency and magnitude of the stapedial reflex was examined in a group of normal-hearing Ss (N: 15) and in 15 Ss with unilateral sensorineural impairment exhibiting abnormal loudness growth in the impaired ear. Reflexes were determined at successive 2-db steps from threshold to 16 db above using a 2-kc/s stimulus tone. Latency and magnitude measurements were not statistically different between groups nor between ears within the pathological group. These results substantiate dependence of the stapedial reflex on loudness. Furthermore, there appears to be a dependence of the reflex magnitude on age, in that the magnitude tends to be less in older Ss.
在一组听力正常的受试者（N = 15）以及15名患单侧感音神经性损伤且患耳响度增长异常的受试者中，检查了镫骨肌反射的潜伏期和幅度。使用2千周/秒的刺激音，从阈值到高于阈值16分贝，以连续2分贝的步长测定反射。潜伏期和幅度测量在两组之间以及病理组内的双耳之间均无统计学差异。这些结果证实了镫骨肌反射对响度的依赖性。此外，反射幅度似乎与年龄有关，因为在年龄较大的受试者中幅度往往较小。
