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.

通常要求对听觉感知的任何经验研究从外围水平开始，尤其是在声学领域。本研究项目试图建立一种系统的方式，将我们的观点转移到更高级别的感知机制上，这与我们的日常体验更加紧密相关。由于听觉感知是我们听觉交流的基础，因此我们经常使用可能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率如何受持续时间标记物的物理特性的影响。我们发现，声音能量对持续时间感知的相对水平或时间分布的系统影响。其次，我们试图找到一般的持续时间感知线索，从而将听觉现象作为差距转移幻觉。我们提出了一个模型，其中声音彼此相互连接，在感知上遵守邻近原理。第三，我们使用由频率调节组件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，我们使用谐波频率滑行建立了间隙传递幻觉。这种刺激模式似乎是调查语音和音乐基本机制的合适材料：感知，我们计划通过引入更复杂的刺激模式将当前的结果与语音和音乐直接联系起来。
