Frequency effects in auditory backward masking were examined by psychophysically determining the thresholds of 0.5-, 1-, 3-, 5-, and 7-kHz sinusoidal probes followed by a broadband noise masker. For each probe frequency, backward masking decreased approximately exponentially as the temporal interval between the probe and masker was increased. The rate of this exponential decay increased with increasing probe frequency. This latter result is consistent with Duifhuis' [J. Acoust. Soc. Am. 54, 1471-1488 (1973)] theory which attributes backward masking to the temporal overlap of cochlear responses to the probe and masker.
通过心理物理学方法确定0.5千赫、1千赫、3千赫、5千赫和7千赫正弦波探测音在宽带噪声掩蔽声之后的阈值，以此研究听觉后向掩蔽中的频率效应。对于每个探测音频率，随着探测音与掩蔽声之间时间间隔的增加，后向掩蔽大致呈指数下降。这种指数衰减的速率随探测音频率的增加而增加。后一个结果与杜伊夫斯[《美国声学学会杂志》54, 1471 - 1488 (1973)]的理论一致，该理论将后向掩蔽归因于耳蜗对探测音和掩蔽声反应的时间重叠。
