The ever-growing body of soundscape research includes studies conducted both in everyday life environments and in laboratory settings. Yet, laboratory settings differ from in-situ and therefore may elicit different perceptions. The present study explores the ecological validity of soundscape reproduction in the laboratory using first-order Ambisonics and of different modes of questionnaire administration. Furthermore, it investigates the influence of the contextual factors of time of day, day of the week, and location on site on soundscape evaluations in situ and in the laboratory, based on the Swedish Soundscape Quality Protocol. We first tested measurement invariance between the computer-based and pen-and-paper administration of the soundscape questionnaire. We then investigated the influence of the above-mentioned contextual factors on soundscape evaluations, as well as the effect of stimuli selection in the laboratory. The analyses confirmed the underlying dimensions of proposed soundscape assessment questionnaires, confirmed metric invariance between computer and pen-and-paper, and revealed significant influences of time, day, and location on soundscape scales. This research represents a critical step in rigorously assessing soundscape evaluations in the laboratory and establishes solid evidence for the use of both in situ and laboratory soundscape studies.
不断增长的声音景观研究包括在日常生活环境和实验室环境中进行的研究。然而，实验室环境与现场环境不同，因此可能会引起不同的感知。本研究使用一阶 Ambisonics 和不同的问卷管理模式，探索了实验室中声音景观再现的生态有效性。此外，根据瑞典声音景观质量协议，本研究还调查了时间、星期几和地点等现场环境因素对现场和实验室中声音景观评价的影响。我们首先测试了基于计算机和纸笔的声音景观问卷管理之间的测量不变性。然后，我们调查了上述环境因素对声音景观评价的影响，以及实验室中刺激选择的效果。分析结果证实了拟议的声音景观评估问卷的潜在维度，证实了计算机和纸笔之间的度量不变性，并揭示了时间、日期和地点对声音景观量表的显著影响。这项研究是在实验室中严格评估声音景观评价的重要步骤，为现场和实验室声音景观研究的使用提供了可靠的证据。
