SBIR Phase I: Enhanced Product Sound Design Choices via Perceptual Attributes Mapping

这个小型企业创新研究（SBIR）第一阶段项目关注消费者对产品声音的偏好，目标是建立一个“映射”或一套工具，产品设计师可以用来实现首选的声音。私家侦探。完成了NSF支持的SGER研究，该研究将产品设计选择与用户对产品声音的反应联系起来。这项研究使用了一个专家小组的听众开发的“感官配置文件”（SP）的有限范围内的产品的声音，和消费者陪审团来判断相同的声音在产品的可接受性。初步的关系已经建立在产品SP和这些声音的物理指标之间，以及产品SP和消费者的判断之间。该项目旨在确定将所开发的方法扩展到扩大的产品声音范围的可行性。三个主要问题的解决，将影响到工业界的概念的效用。一个问题是指标预测用户对产品声音的反应的能力，因为它们与产品SP相关。第二个问题涉及可由特殊产品代表的产品类别的广度。对特定的真空吸尘器和洗衣机的声音的变化已经被用来作为一种方式来发展的想法，但这套需要进一步扩大。第三个问题是关于在同一物理环境中使用的具有不同功能的产品。虽然人们对产品的声音质量有着广泛的商业兴趣，但目前还没有一种结构化的方法让制造商将对声音的偏好与设计目标联系起来。通过开发广泛适用且尽可能易于使用的方法，该研究可以提供可应用于任何声音是问题的产品的声音质量测量程序。

This Small Business Innovation Research (SBIR) Phase I project is concerned with consumer preference for product sound, with the goal of establishing a "mapping" or set of tools that product designers can use to achieve a preferred sound. The P. I. completed a NSF-supported SGER study that related product design choices and user reactions to the sound of the product. This study has used a panel of expert listeners to develop "sensory profiles" (SPs) for a limited range of product sounds, and a consumer jury to judge the same sounds in terms of product acceptability. Preliminary relationships have been established between the product SPs and physical metrics for these sounds, and between the product SPs and consumer judgements. This project seeks to determine the feasibility of extending the methodology developed to an expanded range of product sounds. Three major issues are addressed that will affect the utility of the concept as far as industry is concerned. One issue is the ability of metrics to anticipate user reactions to product sound because of their correlation with the product SPs. The second issue relates to the breadth of a product class that can be represented by a SPs. Variations on the sounds of particular vacuum cleaners and washing machines have been used as a way to develop the ideas, but this set needs to be expanded further. The third issue is concerned with products with different function but which are used in the same physical environment. While there is widespread commercial interest in product sound quality, there is at present no structured way for manufacturers to relate the preference for sound to design goals. By developing methods that are broadly applicable and as easy to use as possible, the research can provide sound quality measurement procedures that can be applied to any product for which sound is an issue.
