在此之前，英国没有结构化的机制来评估开放空间的听觉和视觉刺激特性。这在很大程度上是因为，在“宁静”的环境中，人们对视听方式的相互作用以及它们如何联合收割机产生宁静感知之甚少。本文介绍了一项研究的结果，其中的视觉和声学数据，从I I英语农村和城市景观捕获，被44名志愿者使用，他们的位置的感知安宁，和五个通用的声景组件的响度进行主观评估。然后将结果与实验室中进行的客观测量一起进行分析。结果发现，最大声压级（L-Amax）和一个位置的自然特征的百分比是影响宁静的关键因素。提出了作为噪声水平和自然特征比例的函数的宁静度的工程公式。(C)2008年，美国声学学会。
Prior to this work no structured mechanism existed in the UK to evaluate the tranquillity of open spaces with respect to the characteristics of both acoustic and visual stimuli. This is largely due to the fact that within the context of "tranquil" environments, little is known about the interaction of the audio-visual modalities and how they combine to lead to the perception of tranquillity. This paper presents the findings of a study in which visual and acoustic data, captured from I I English rural and urban landscapes, were used by 44 volunteers to make subjective assessments of both their perceived tranquillity of a location, and the loudness of five generic soundscape components. The results were then analyzed alongside objective measurements taken in the laboratory. It was found that the maximum sound pressure level (L-Amax and the percentage of natural features present at a location were the key factors influencing tranquillity. Engineering formulas for the tranquillity as a function of the noise level and proportion of the natural features are proposed. (C) 2008 Acoustical Society of America.
