On the mechanism of rhythm perception as a basis of auditory communication

在声学领域，通常要求任何听觉感知的实证研究都是从外围水平开始的。目前的研究项目是试图建立一种系统的方法，将我们的观点转移到更高层次的感知机制，这与我们的日常经验更密切相关。因为听觉感知是我们听觉交流的基础，我们经常使用可能与言语或音乐有关的材料。首先，我们研究了持续时间或持续时间比率的感知如何受到持续时间标记物的物理性质的影响。我们发现声能量的相对水平或时间分布对持续时间感知的系统影响。其次，我们试图从总体上寻找持续时间感知的线索，研究作为间隙转移错觉的听觉现象。我们提出了一个模型，在这个模型中，声音的开始和结束在感知上遵循接近原则相互连接。第三，我们利用由调频成分组成的刺激模式研究了听觉组织的原理。检查了组件之间的感知相互作用。最近，我们利用谐波频率滑动建立了间隙转移错觉。这种刺激模式似乎是研究语言和音乐的基本机制：感知的合适材料，我们正计划通过引入更复杂的刺激模式将目前的结果直接与语言和音乐联系起来。

It had been often required that any empirical study of auditory perception start from the peripheral level especially in the field of acoustics. The present research project was an attempt to establish a systematic way to shift our viewpoint to the perceptual mechanism at a higher level, which is more closely related to our everyday experience. Because auditory perception is the basis of our auditory communication, we often used materials which could be related to speech or music. Firstly, we investigated how the perception of duration or: duration ratio is affected by the physical properties of duration markers. We found systematic effects of relative levels or temporal distributions of sound energy on duration perception. Secondly, we tried to find the cues of duration perception in general, studying auditory phenomena as the gap transfer illusion. We proposed a model, in which onsets and terminations of sounds are connected each other perceptually obeying the proximity principle. Thirdly, we investigated the principles of auditory organization using stimulus patterns consisting of frequency-modulated components. Perceptual interactions between the components were examined. Recently, we established the gap transfer illusion using harmonic frequency glides. Stimulus patterns of this kind seem to be suitable materials to investigate the basic mechanism of speech and music: perception, and we are planning to connect the present results directly with speech and music by introducing more complex stimulus patterns.
