Auditory thresholds were determined for 500 HZ pure tone pulses of 15, 25 and 50 ms duration presented leading, following or simultaneously with noise pulses of 50 or 250 ms duration. Masking by the noise decreased: (i) with an increase in tone pulse duration; (ii) with a shortening of the noise pulse duration; and (iii) as the interval between tone and noise pulses was increased from 0 to 350 ms. The effect of the noise was independent of whether the noise led or followed the pure tone. It is suggested that the most significant factor affecting masking was the duration of the interval between tone and noise, and that the site for the interactions between signals is central to the inner ear.
针对持续时间为15、25和50毫秒的500赫兹纯音脉冲进行听觉阈值测定，这些纯音脉冲在持续时间为50或250毫秒的噪声脉冲之前、之后或同时呈现。噪声掩蔽效应降低：（i）随着纯音脉冲持续时间的增加；（ii）随着噪声脉冲持续时间的缩短；以及（iii）随着纯音和噪声脉冲之间的间隔从0增加到350毫秒。噪声的影响与噪声是先于还是后于纯音无关。研究表明，影响掩蔽的最重要因素是纯音和噪声之间的间隔持续时间，并且信号之间相互作用的部位在内耳中心。
