人们对建筑环境有情感反应，而声环境是人们对场所体验的主要因素之一。这对于决策者，如规划师、建筑师、工程师和设计师来说，了解建成环境的声音景观与他们在这些环境中的用户所产生的情感反应之间的联系是很有用的。这种理解可以让这些决策者做出关于建筑环境设计的更明智的决定，并实现用户期望的积极情感反应。所讨论的问题，也是本文的主题，是理解和定义声音场景的情感维度，然后探索合成的维度空间如何在决策中具有实际应用。通过积极声景观项目产生的数据，进行主成分分析，将城市声景观的描述符分解为两个独立的情感维度。研究发现，音景的两个独立的情感维度与其“平静”和“活力”有关，这两个维度可以用来描述一个二维的知觉空间。然后进行听力评估，以探索不同类型的城市声景观的感知如何与2D情感感知空间相关联，并说明(I)引入设计干预措施如何改变声景观在该空间中的位置，以及(Ii)诸如分贝(A)等指标如何与平静和活力分数不一定相关。通过举例说明，我们建议这样的二维感知空间如何在规划过程中具有实际用途，主要是作为一种手段，以简单、可视和易于比较的方式呈现用户对音景的感知，并为当前和未来的音景设计设定目标。最后，我们对进一步的工作提出了建议，以充分发展这些情感维度和二维感知空间，使之成为一个有用的工具。(C)2011爱思唯尔有限公司。保留所有权利。
People have emotional reactions to the built environment, and the sonic environment is one of the major contributing factors of people's experiences of places. It is useful for decision makers such as planners, architects, engineers and designers to understand the link between the soundscapes of built environments, and their resultant emotional reactions within users of those environments. This understanding can allow these decision makers to make better informed decisions about built environment design, and achieve the desired positive emotional responses from users. The issue under question, and the subject of this paper, was to understand and define the emotional dimensions of a soundscape, and then to explore how the resultant dimensional space could have a practical application in decision making. Through data generated through the Positive Soundscapes Project, a Principal Component Analysis was conducted to decompose descriptors of the urban soundscape into two independent emotional dimensions. It was found that the two independent emotional dimensions of a soundscape relate to its "Calmness" and "Vibrancy", and these could be positioned to describe a 2-Dimensional (2-D) perceptual space. Listening evaluations were then conducted to explore how perceptions of different types of urban soundscape could be plotted with the 2D emotional perceptual space, and to illustrate how (i) introducing design interventions can change the position of soundscapes within this space and (ii) how metrics such as dB(A) do not necessarily correlate with calmness and vibrancy scores. Through illustrative examples, we suggest how such a 2-D perceptual space might have a practical use in the planning process, primarily as a means for presenting users' perceptions of soundscapes in a simple, visual, and easy to compare manner, and for setting targets for current and future soundscape design. We conclude with recommendations for further work required to fully develop these emotional dimensions and the 2-D perceptual space into a useful tool. (C) 2011 Elsevier Ltd. All rights reserved.
