Rate versus level functions are presented for auditory-nerve fiber responses to best frequency (BF) tones presented alone and in the presence of a constant level suppressor tone. The paper focuses on units with sloping saturation rate functions for BF tones presented alone. Two-tone rate functions are generally parallel to BF functions at firing rates below those in the sloping saturation region of the BF function. At rates in the sloping saturation range the two-tone function grows with a greater slope than that of the BF function until the two functions meet. This result is discussed in terms of current knowledge of two-tone suppression on the basilar membrane.
本文给出了听神经纤维对单独呈现的最佳频率（BF）纯音以及在存在恒定强度抑制性纯音情况下的反应的发放率与强度函数。本文聚焦于对单独呈现的BF纯音具有斜率饱和发放率函数的单元。在低于BF函数斜率饱和区域的发放率下，双音发放率函数通常与BF函数平行。在斜率饱和范围内的发放率下，双音函数的增长斜率比BF函数的更大，直到两个函数相交。根据目前关于基底膜上双音抑制的知识对这一结果进行了讨论。
