Eyeblink reflexes to airpuffs to the orbit are inhibited by preliminary tones even of low intensity, and the amount of inhibition or "reflex modulation" (RM) is correlated with tone loudness. Brief pure tones were presented 100 msec prior to an airpuff to the eye and eyeblink amplitude was recorded in 7 normal-hearing adults. Tones of several levels were either in quiet or in a white noise of 73.5 dbC. As tones increased in intensity, RM increased faster to stimulation in the masked than in the unmasked ear, simulating the classical "pseudo-recruitment" in the noise-masked ear. In addition, very rapid growth of RM was found at 4 kc/s in a patient with sensorineural impairment of 70 db at that frequency as compared with the RM from a frequency with normal HTL. These data confirm the potential of RM in the objective quantification of loudness recruitment.
即使是低强度的预备音也会抑制对眼眶吹气的眨眼反射，并且抑制量或“反射调制”（RM）与音高相关。在对眼睛吹气前100毫秒呈现短暂的纯音，并记录7名听力正常的成年人的眨眼幅度。几个强度级别的纯音分别在安静环境中或73.5分贝C的白噪声环境中呈现。随着音强增加，与未掩蔽耳相比，掩蔽耳中RM对刺激的增加速度更快，模拟了噪声掩蔽耳中的经典“伪重振”。此外，与正常听力阈值水平的频率相比，在一名该频率听力损失70分贝的感音神经性损伤患者中，在4千赫时发现RM增长非常迅速。这些数据证实了RM在响度重振客观量化方面的潜力。
