项目摘要

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.

听觉感知的实验研究往往要求从听觉的外周水平开始，尤其是在声学领域。本研究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。因为听觉是我们听觉交流的基础，所以我们经常使用与语音或音乐有关的材料。首先，我们研究了持续时间或持续时间比的感知如何受到持续时间标记的物理特性的影响。我们发现系统的相对水平或时间分布的声音能量持续感知的影响。其次，我们试图从总体上寻找持续知觉的线索，将听觉现象作为差距传递错觉来研究。我们提出了一个模型，在这个模型中，声音的起始和终止在感知上遵循邻近原则相互连接。第三，我们使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，我们建立了差距转移错觉，利用谐波频率下滑。这种刺激模式似乎是研究语音和音乐的基本机制的合适材料：感知，我们正计划通过引入更复杂的刺激模式将目前的结果与语音和音乐直接联系起来。
