迭代涟漪噪声（IRN）是一种具有时域特性的宽带噪声，它能产生可感知的基音周期。由于可以改变这些刺激的感知音高噪声比而基本上不改变它们的频谱内容，因此它们在探索音高感知中的时间处理的作用中是有用的[Yost，W.A.，1996.迭代波纹噪声的音调强度，J. Acoust。美国社会100（5），3329-3335; Patterson，R.D.，Handel，S.，约斯特，西弗吉尼亚州，Datta，AT，1996年。迭代波纹噪声中音调和噪声分量的相对强度，J. Acoust。美国社会100（5），3286-3294]。提出了一种广义的IRN算法，其中可以定义多个时变时间相关。所得到的时变音高在感知上是非常显著的。还可以分离和跟踪这些刺激中的多个同时时变音高。时间听觉模型先前已被证明可以解释具有静态延迟的IRN的感知[Patterson，R.D.，Handel，S.，约斯特，西弗吉尼亚州，达塔，A. J.，1996.迭代波纹噪声中音调和噪声分量的相对强度，J. Acoust。美国社会100（5），3286-3294]。在这里，我们表明，一些简单的修改，一个这样的模型[Meddis R.，休伊特，M. J.，1991.听觉外围计算机模型的虚拟音调和相位灵敏度I。音高识别，J. Acoust。美国社会89，2866-2882]允许其跟踪移动相关性，并且还提高其响应性能。静态相关性。(C)2004爱思唯尔爱尔兰有限公司保留所有权利。
Iterated ripple noise (IRN) is a broadband noise with temporal regularities, which can give rise to a perceptible pitch. Since the perceptual pitch to noise ratio of these stimuli can be altered without substantially altering their spectral content, they have been useful in exploring the role of temporal processing in pitch perception [Yost, W.A., 1996. Pitch strength of iterated rippled noise, J. Acoust. Soc. Am. 100 (5), 3329-3335; Patterson, R.D., Handel, S.,Yost, W.A., Datta, AT, 1996. The relative strength of the tone and noise components in iterated rippled noise, J. Acoust. Soc. Am. 100 (5), 3286-3294]. A generalised IRN algorithm is presented, in which multiple time varying temporal correlations can be defined. The resulting time varying pitches are perceptually very salient. It is also possible to segregate and track multiple simultaneous time varying pitches in these stimuli. Temporal auditory models have previously been shown to account for the perception of IRNs with static delays [Patterson, R.D., Handel, S.,Yost, W.A., Datta, A.J., 1996. The relative strength of the tone and noise components in iterated rippled noise, J. Acoust. Soc. Am. 100 (5), 3286-3294]. Here we show that some simple modifications to one such model [Meddis R., Hewitt, M.J., 1991. Virtual pitch and phase sensitivity of a computer model of the auditory periphery I. Pitch identification, J. Acoust. Soc. Am. 89, 2866-2882] allow it to track moving correlations, and also improve its performance in response. to static correlations. (C) 2004 Elsevier Ireland Ltd.
