项目摘要
The child's cry that wakes you in night is not hard to identify. The footfalls and hoof beats in a western movie supply crucial realism to the moviegoer. Things that make noise are tightly woven into the fabric of human experience. Nevertheless, we know very little about the actual perception of auditory events. This is true despite our extensive knowledge of how ears work, for example, and our extensive knowledge about the basic auditory capabilities of ourselves and other animals. The specialized area of speech perception has made some advances, but the perception of our environment involves sounds other than speech, and the study of human speech has provided few insights into how we perceive complex acoustic events.The impact of a shoe on a wooden floor will sound differently than the same shoe on a metal floor. Acoustic properties of auditory events reflect physical and biomechanical properties of their sources. To understand auditory event perception, the funded project will identify the physical and biomechanical properties of source events and then identify relations between these source properties and the acoustic properties of the resulting sound. With this database in hand, Dr. Pastore and his colleagues will next conduct experiments to identify the sound attributes that listeners correctly (or incorrectly) associate with source properties. Specifically, the funded project employs this source-sound-perception approach to investigate human gait as a class of auditory events. Although the proposed research focuses on human gait as a source of sounds, the overarching goal is to develop research procedures to study perception of almost any auditory event.This basic research has broad implications. For example, virtual-reality technology has fostered interests in the development of auditory virtual-reality capabilities. The funded basic research will accomplish the crucial first step to make such applications possible. This research could also contribute to the development of effective surveillance systems for research, commercial, and military use. Moreover, it will identify how listening skills may be improved with training and which attributes of sounds are most important to aid the hearing impaired.
夜里把你吵醒的孩子的哭声并不难辨认。 西部电影中的脚步声和马蹄声为观众提供了至关重要的现实主义。 制造噪音的东西紧密地编织在人类经验的结构中。 然而,我们对听觉事件的实际感知知之甚少。 这是真的,尽管我们对耳朵如何工作有广泛的了解,例如,我们对自己和其他动物的基本听觉能力有广泛的了解。 言语感知的专门领域已经取得了一些进展,但我们对环境的感知涉及语音以外的声音,而对人类言语的研究几乎没有提供我们如何感知复杂声学事件的见解,一只鞋在木地板上的声音与同一只鞋在金属地板上的声音不同。 听觉事件的声学特性反映了其声源的物理和生物力学特性。 为了理解听觉事件感知,该资助项目将识别源事件的物理和生物力学特性,然后识别这些源特性与所产生声音的声学特性之间的关系。 有了这个数据库,Pastore博士和他的同事接下来将进行实验,以确定听众正确(或错误)与源属性相关联的声音属性。 具体而言,资助的项目采用这种源声音感知方法来研究人类步态作为一类听觉事件。 虽然拟议的研究重点是人类步态作为声音的来源,总体目标是开发研究程序,研究几乎任何听觉事件的感知。 例如,虚拟现实技术已经培养了人们对开发听觉虚拟现实能力的兴趣。 受资助的基础研究将完成使此类应用成为可能的关键的第一步。 这项研究还有助于开发用于研究、商业和军事用途的有效监测系统。 此外,它还将确定如何通过培训提高听力技能,以及声音的哪些属性对帮助听力受损者最重要。
