SGER: Mapping Perceptual Attibutes of Sound to Product Design Choices

PI/机构：Richard Lyon， R.H. Lyon公司提案号：9909166标题：将声音的感知属性映射到产品设计选择这个探索性研究（SGER）项目需要研究消费者对产品声音的偏好，目标是建立一种语言或词汇来映射消费者对产品声音的偏好，这种偏好适合产品设计师使用，以实现首选的声音。目前，对于声学工程师来说，还没有结构化的过程可以用来将消费者的声音偏好与产品工程设计目标联系起来。本研究中用于理解和量化产品声音的过程建立在心理声学中常用的聆听小组（陪审团测试）方法的基础上。与内容自由刺激（点击，音调，随机噪音）旨在避免刺激中认知内容的复杂性相反，本研究使用专家小组来探索各种声音属性并开发适合建立适合机器声音的“声音语言”的描述符。然后，PI将声音描述符与源属性相关联，并开发刺激的物理度量，从而为工程师提供有意义的产品设计输入。从对声音感知属性的理解中发展出来的新工具为建立一套工具提供了基础，产品设计师可以使用这些工具来实现首选的产品声音属性。

PI/Institution: Richard Lyon, R.H. Lyon Corp.Proposal Number: 9909166Title: Mapping Perceptual Attributes of Sound to Product Design ChoicesThis Small Grant for Exploratory Research (SGER) project entails study of consumer preference for product sound with the goal of establishing a language or vocabulary to map consumer preferences for product sound that is appropriate for use by product designers to achieve a preferred sound. At present there is no structured process available for acoustic engineers to use to relate consumer sound preferences to product engineering design goals. The process used in this study for understanding and quantifying product sounds build on the methods of listening panels (jury tests) that are in common use in psychoacoustics. As opposed to the content free stimuli (clicks, tones, random noise) intended to avoid the complexities of cognitive content in the stimuli, this study uses an expert panel to explore a variety of sounds attributes and develop descriptors appropriate for establishing a "language of sound" appropriate for machine sounds. The PI then will correlate sound descriptors to source attributes and develop physical metrics of stimuli that can provide engineers meaningful product design input. New tools developed from an understanding of sound perception attributes as proposed provides the foundation for establishing a set of tools that product designers can use to achieve preferred product sound attributes.
