论文摘要
在本文中，Dau等人开发的听觉模型。 [J。声音。 Soc。是。 102，2892-2905（1997）]用于模拟复杂声音之间的感知相似性。为此，开发并将中央处理器阶段作为听觉模型的后端模块。作为复杂的声音，使用了一组在七个不同的钢琴上播放的音符的录音，最近通过Osses等人测量了它们的相似性。 [J。声音。 Soc。是。 146，1024-1035（2019）]使用噪声中的3-AFC歧视任务。听觉模型具有多个处理阶段，这些处理阶段或多或少受到人类正常听力系统的生理方面的启发。每个阶段中的一组可配置参数直接影响在开发的中央处理器中进一步处理的声音（内部）表示。因此，对模型参数进行了全面审查，表明我们选择的配置。这包括对听觉适应阶段的深入描述，即适应环。将相似性任务的模拟与（1）现有的实验数据进行了比较，它们具有中等至高相关性，以及（2）使用替代性但背景噪声与实验相似的模拟，这些噪声与实验相似，这些噪声用于获取有关如何将参与者的响应加权作为频率函数的进一步信息。
In this paper the auditory model developed by Dau et al. [J. Acoust. Soc. Am. 102, 2892-2905 (1997)] was used to simulate the perceptual similarity between complex sounds. For this purpose, a central processor stage was developed and attached as a back-end module to the auditory model. As complex sounds, a set of recordings of one note played on seven different pianos was used, whose similarity has been recently measured by Osses et al. [J. Acoust. Soc. Am. 146, 1024-1035 (2019)] using a 3-AFC discrimination task in noise. The auditory model has several processing stages that are to a greater or lesser extent inspired by physiological aspects of the human normal-hearing system. A set of configurable parameters in each stage affects directly the sound (internal) representations that are further processed in the developed central processor. Therefore, a comprehensive review of the model parameters is given, indicating the configuration we chose. This includes an in-depth description of the auditory adaptation stage, the adaptation loops. Simulations of the similarity task were compared with (1) existing experimental data, where they had a moderate to high correlation, and with (2) simulations using an alternative but similar background noise to that of the experiments, which were used to obtain further information about how the participants' responses were weighted as a function of frequency.
