For the purpose of this study, acoustic signals were generated by an Amplaid MK VI. An Amplaid 702 impedence meter was connected to its averaging section and to its computer. The stimuli were bursts of unfiltered white noise (UWN) and of narrow band white noise (NBWN; 30 db./oct/slope; central frequencies 1,000, 2,000, 4,000 Hz.) lasting 3-1,000 msec., at intensity of 105 db. SPL p.e. The following parameters were evaluated: stapedius contraction latency, amplitude, duration and recruitment time. It was found that latency was independent of the spectrum of the stimulus and its duration. Amplitude and recruitment time, on the other hand, were related to spectrum and duration, while duration of contraction was directly related to the duration of the stimulus only.
为了本研究的目的，声学信号由一台Amplaid MK VI产生。一台Amplaid 702阻抗计连接到其平均部分和计算机。刺激为持续3 - 1000毫秒、强度为105分贝声压级峰值等效连续声级的未滤波白噪声（UWN）和窄带白噪声（NBWN；30分贝/倍频程/斜率；中心频率1000、2000、4000赫兹）脉冲串。评估了以下参数：镫骨肌收缩潜伏期、幅度、持续时间和重振时间。发现潜伏期与刺激的频谱及其持续时间无关。另一方面，幅度和重振时间与频谱和持续时间有关，而收缩持续时间仅与刺激的持续时间直接相关。
