Psychophysical and acoustic reflex temporal summation measures were obtained on normal-hearing and sensorineural hearing-impaired persons. Bursts of one-third octave noise with center frequencies of 500, 1000, 2000, and 4000 Hz and durations of 15, 20, 50, 100, 200, and 300 msec were used as stimuli. Reflexes were obtained using an acoustic impedance measuring technique. Results demonstrated that the duration of the noise stimuli had a profound effect on the acoustic reflex response and that the ear with Ménière's disease was clearly distinguishable from the normal ear by both psychophysical and acoustic reflex temporal summation measurements. The presbycusic subjects were separated from the normal subjects to a greater extent in the psychophysical data at the higher frequencies. The reflex thresholds for the noise bands and durations used in this study occurred at lower sound pressure levels than those previously obtained. The normal-hearing subjects failed to show any differences in either psychophysical or acoustic reflex temporal summation as a function of stimulus frequency.
对听力正常者和感音神经性听力受损者进行了心理物理学和听觉反射时间总和测量。以中心频率为500、1000、2000和4000Hz、持续时间为15、20、50、100、200和300毫秒的1/3倍频程噪声脉冲作为刺激。使用声阻抗测量技术获得反射。结果表明，噪声刺激的持续时间对听觉反射反应有深远影响，通过心理物理学和听觉反射时间总和测量，梅尼埃病患者的耳朵与正常耳朵明显可区分。在较高频率的心理物理学数据中，老年聋受试者与正常受试者的分离程度更大。本研究中使用的噪声频段和持续时间的反射阈值出现在比以前获得的更低的声压水平。听力正常的受试者在心理物理学或听觉反射时间总和方面均未表现出随刺激频率的任何差异。
