摘要

绿色空间对居民来说是必不可少的，因为接触绿色空间有助于提高认知能力。本研究通过室外实验，探讨声压级（SPL）、声源优势度（SSD）及其相互作用对绿色空间中认知表现和声环境感知的影响。研究收集了118名被试在3种声压级(55 dB(a)、60 dB（a)和65 dB(a)）和4种固态硬盘（鸟类固态硬盘、人类喋喋声固态硬盘、交通固态硬盘和建筑固态硬盘）和安静条件下（共13种实验条件）的认知表现和环境感知。评估了七种认知能力：记忆（m -能力）、注意（a -能力）、计划（p -能力）、空间（s -能力）、注意-记忆（am -能力）、计划-记忆（pm -能力）和空间记忆（sm -能力）。结果表明，绿地环境下的认知任务类型不同，SSD和SPL对认知表现有显著影响。改善声环境感知的声学条件并不总是与更好的认知表现相对应。在特定声压级条件下，绿色空间中特定类型的噪音甚至可以增强认知能力。在p能力和am能力相关的任务中，SPL和SSD对认知表现有显著的交互作用。此外，在声环境舒适度（AEC）和声景观愉悦度（SP）方面，声压级和声压级对声环境感知有显著的交互作用。这些研究结果可以加深我们对声环境如何影响绿地的认知表现和声环境感知的理解，为绿地声环境的设计和管理提供有价值的参考。

The effects of sound source dominance and pressure level on cognitive performance and environmental perception in green space

Green spaces are essential for inhabitants, as exposure to them can be beneficial to cognitive performance. This research conducted an outdoor experiment to explore the effects of acoustic environments, including sound pressure level (SPL), sound source dominance (SSD), and their interaction, on cognitive performance and acoustic environmental perception in a green space. Cognitive performances and environmental perceptions of 118 participants were collected under a combination of 3 SPLs (55 dB(A), 60 dB(A), and 65 dB(A)) and 4 SSDs (bird SSD, human chatter SSD, traffic SSD, and construction SSD) and a quiet condition (totaling 13 experimental conditions). Seven cognitive abilities were assessed: memory (M-ability), attention (A-ability), planning (P-ability), spatial (S-ability), attention-memory (AM-ability), planning-memory (PM-ability), and spatial-memory (SM-ability). The results showed that SSD and SPL can significantly affect cognitive performance in green space, with the impacts varying depending on the types of cognitive tasks. Acoustic conditions that improve acoustic environmental perception do not always correspond to better cognitive performance. Under certain SPL conditions, specific types of noise within green spaces can even enhance cognitive performance. Significant interaction effects between SPL and SSD on cognitive performance were observed in tasks related to P-ability and AM-ability. Furthermore, significant interaction effects between SPL and SSD on acoustic environmental perception were noted in terms of acoustic environment comfort (AEC) and soundscape pleasantness (SP). These findings can enhance our understanding of how the acoustic environment influences cognitive performance and acoustic environmental perception in green spaces, providing valuable references for the design and management of acoustic environments in green spaces.

期刊介绍： Since its launch in 1968, Applied Acoustics has been publishing high quality research papers providing state-of-the-art coverage of research findings for engineers and scientists involved in applications of acoustics in the widest sense. Applied Acoustics looks not only at recent developments in the understanding of acoustics but also at ways of exploiting that understanding. The Journal aims to encourage the exchange of practical experience through publication and in so doing creates a fund of technological information that can be used for solving related problems. The presentation of information in graphical or tabular form is especially encouraged. If a report of a mathematical development is a necessary part of a paper it is important to ensure that it is there only as an integral part of a practical solution to a problem and is supported by data. Applied Acoustics encourages the exchange of practical experience in the following ways: • Complete Papers • Short Technical Notes • Review Articles; and thereby provides a wealth of technological information that can be used to solve related problems. Manuscripts that address all fields of applications of acoustics ranging from medicine and NDT to the environment and buildings are welcome.
