时间包络的跨频率比较可能是听觉模式分析的一般特征，并且可能在从嘈杂背景中提取信号或分离竞争声源方面发挥重要作用。背景噪声中不同频带的调制有助于噪声中音调的检测，这种现象称为调制掩蔽释放（CMR）。最近有兴趣阐明CMR可能的生理基础（Nelken, Rotman, and Bar Yosef, 1999; Pressnitzer, Meddis, Delahaye, and Winter, 2001），并确认其在非人类物种中的存在（例如，Klump and Langemann, 1995）。CMR有两种测量方法。第一种方法是使用以信号频率为中心的单波段噪声作为掩模，并比较调制和未调制掩模的阈值作为掩模带宽的函数（例如，Hall, Haggard, and Fernandes 1984； Schooneveldt和Moore 1989； Carlyon, Buus, and Florentine 1989）。第二种方法是使用由几个狭窄的掩膜带组成的掩膜，一个在信号频率（非频带），另一个或多个与非频带分离的其他频带（侧翼频带）（例如，Hall et al. 1984; Hall, grosse, and Haggard 1990; Schooneveldt and Moore 1987）。
Across-frequency comparisons of temporal envelopes are likely to be a general feature of auditory pattern analysis and may play an important role in extracting signals from noisy backgrounds, or in separating competing sources of sound. Comodulation of different frequency bands in background noise facilitates the detection of tones in noise, a phenomenon known as comodulation masking release (CMR). There has been recent interest in elucidating the possible physiological basis for CMR (Nelken, Rotman, and Bar Yosef 1999; Pressnitzer, Meddis, Delahaye, and Winter 2001) and in confirming its presence in non-human species (eg, Klump and Langemann 1995).CMR has been measured in two ways. The first is to use a single band of noise, centered around the signal frequency, as a masker and to compare thresholds for modulated and unmodulated maskers as a function of the masker bandwidth (eg, Hall, Haggard, and Fernandes 1984; Schooneveldt and Moore 1989; Carlyon, Buus, and Florentine 1989). The second method is to use a masker consisting of several narrow masker bands, one at the signal frequency (on-frequency band) and one or more other bands (flanking bands) spectrally separated from the on-frequency band (eg, Hall et al. 1984; Hall, Grose, and Haggard 1990; Schooneveldt and Moore 1987).
