摘要
声景方法已在最近的住宅环境研究中得到应用,但在室内工作环境中的应用仍然有限。本研究调查了对开放式办公室声学进行情感质量评估的适用性。使用 PD ISO/TS 12913-3:2019 和室内声景研究中概述的情感维度,由八个开放式办公室平面的使用者完成感知评估。收集了参与者的人口统计学、环境、工作相关质量和心理健康数据。工作站噪音水平按照 BS ISO 22955:2021 进行测量。主成分分析确定了愉悦感、事件性和空虚感是主要的感知维度,累计解释了总方差的 56%。结果表明,PD ISO/TS 12913-3:2019 二维模型适用于开放式办公室。感知到的人声与 ISO 愉快度呈负相关,但与 ISO 事件性呈正相关。参与者的性别和听觉多样性对 ISO 愉快度具有中介作用。心理健康和工作相关质量与声景愉悦度呈正相关。基于声级的声学指标--等效连续声级(LAeq)、超过 10%(LA10)和 90%(LA90)的声级、声级变异性(LA10-LA90)和活泼度--与感知评分之间没有相关性。本文提出了开放式办公室声景感知的概念表述,为评估和设计工作空间提供了一个框架,以提高舒适度。
Office soundscape assessment: A model of acoustic environment perception in open-plan officesa).
The soundscape approach has been utilised in recent research for residential environments, but applications to indoor working environments remain limited. This study investigated the suitability of affective quality evaluations of open-plan office acoustics. Perceptual assessments were completed by occupants of eight open-plan office floorplates, using affective dimensions outlined in PD ISO/TS 12913-3:2019 and indoor soundscape studies. Participant demographic, contextual, work-related quality, and psychological well-being data were collected. Workstation noise levels were measured following BS ISO 22955:2021. Principal component analysis identified Pleasantness, Eventfulness, and Emptiness as the main perceptual dimensions, cumulatively explaining 56% of the total variance. Results indicate the suitability of the PD ISO/TS 12913-3:2019 two-dimensional model for open-plan offices. The perceived presence of human sounds negatively correlated with ISO Pleasantness yet positively correlated with ISO Eventfulness. Participant gender and aural diversity mediated ISO Pleasantness. Psychological well-being and work-related quality correlated positively with soundscape pleasantness. No correlations were found between level-based acoustical indicators-equivalent continuous sound level (LAeq), level exceeded 10% (LA10) and 90% (LA90) of the time, level variability (LA10-LA90) and Liveliness-and perceptual scores. A conceptual representation of open-plan office soundscape perception is presented, offering a framework for evaluating and designing workspaces to enhance well-being.
