Previous research (Emmerich et al., 1983) in which tones were presented in the center of the notches in band-reject noise backgrounds suggests that information from frequency regions remote from the nominal signal frequency is useful in frequency discrimination. The present work extends the earlier findings by presenting tones on either side of a notch so that only one (or the other) tail of the excitation patterns of the tones would fall into the notch. In addition, tones were presented in high-pass noise, low-pass noise, and various combinations of the two. The results again indicate that remote information affects frequency discrimination, and they are also consistent with the hypothesis that the low-frequency tail of the excitation pattern is more useful for frequency discrimination than is the high-frequency tail.
先前的研究（埃默里希等人，1983年）在带阻噪声背景下的陷波中心呈现音调，这表明来自远离标称信号频率的频率区域的信息在频率辨别中是有用的。目前的工作通过在陷波的两侧呈现音调来扩展早期的研究结果，这样音调的激发模式的只有一个（或另一个）尾部会落入陷波中。此外，音调还在高通噪声、低通噪声以及两者的各种组合中呈现。结果再次表明远程信息会影响频率辨别，并且它们也与这样的假设一致，即激发模式的低频尾部在频率辨别中比高频尾部更有用。
