The purpose of the present study was to examine the functional between acoustic reflex (AR) latency and the intensity and frequency of the eliciting stimulus. AR latency was determined at various intensities for 500 Hz and 300 Hz pure tones, and for wide-band noise. The results of the study indicated that AR latency decreased as stimulus intensity increased for all stimuli; the exact nature of the relationship depended on the stimulus, however. Latency differences between the stimuli at a given sound pressure level tended to disappear at higher presentation levels. Of particular interest was the dependency of inter- and intrasubject variability on parameters of the eliciting stimulus. The data do no indicate that AR latency is mediated solely by the loudness of the eliciting stimulus.
本研究的目的是检验听觉反射（AR）潜伏期与诱发刺激的强度和频率之间的功能关系。在500Hz和300Hz纯音以及宽带噪声的不同强度下测定AR潜伏期。研究结果表明，对于所有刺激，随着刺激强度增加，AR潜伏期缩短；然而，这种关系的确切性质取决于刺激类型。在给定声压水平下，不同刺激之间的潜伏期差异在较高呈现水平时往往会消失。特别值得关注的是，个体间和个体内变异性对诱发刺激参数的依赖性。数据并未表明AR潜伏期仅由诱发刺激的响度介导。
