声景研究需要为环境设计开发预测工具。到目前为止，已经提出了许多描述-指标模型，特别是用于管理城市环境中“安静区域”的“宁静”维度。然而，目前还缺乏能够提供积极的声音场景的模型，即“活力”维度。本研究的主要目的是建立一个基于物理参数的振动描述符预测模型，供设计人员和从业人员使用。我们进行了一次小组访谈，以制定一个关于哪些因素会影响活力感知的假设。随后，通过实验室实验收集了英国和中国不同地点的振动感知数据，并以其物理参数为指标建立预测模型。这些指标包括听觉和视觉参数。该模型基于粗糙度、人的存在、波动强度、响度和音乐的存在作为预测指标，解释了平均个人活力得分中76%的差异。活力得分与事件得分之间存在统计学上的显著相关性，但活力得分与愉悦得分之间没有统计学上的显著相关性。总体结果表明，活力与环境有关，既取决于声景，也取决于视觉景。
Soundscape research needs to develop predictive tools for environmental design. A number of descriptor-indicator(s) models have been proposed so far, particularly for the “tranquility” dimension to manage “quiet areas” in urban contexts. However, there is a current lack of models addressing environments offering actively engaging soundscapes, i.e., the “vibrancy” dimension. The main aim of this study was to establish a predictive model for a vibrancy descriptor based on physical parameters, which could be used by designers and practitioners. A group interview was carried out to formulate a hypothesis on what elements would be influential for vibrancy perception. Afterwards, data on vibrancy perception were collected for different locations in the UK and China through a laboratory experiment and their physical parameters were used as indicators to establish a predictive model. Such indicators included both aural and visual parameters. The model, based on Roughness, Presence of People, Fluctuation Strength, Loudness and Presence of Music as predictors, explained 76% of the variance in the mean individual vibrancy scores. A statistically significant correlation was found between vibrancy scores and eventfulness scores, but not between vibrancy scores and pleasantness scores. Overall results showed that vibrancy is contextual and depends both on the soundscape and on the visual scenery.
