本研究旨在探讨在不同的空间功能中，声景与景观之间的关系，并探讨在城市环境中，场所的功能方面对声景感知的影响。在首尔的25个地点进行了调查，以评估声景和景观感知。根据空间的主要功能、活动和视觉特性，将城市环境分为四类：商业、住宅、商业和娱乐。从交通、人、自然声源、宜人性、视觉质量、环境和谐性等7个方面构建了城市声景观的结构方程模型。该模型与调查中测得的数据拟合良好。结果表明，影响声景观的主导因素因场所的主要功能而异。在商业区，人类活动的声音在评价声景方面发挥了重要作用。对于居住和商业功能区，交通噪声是影响声景观质量的主要声源。此外，休闲活动中的人类声音在城市休闲区相关声景观的构建中发挥着重要作用。研究结果为理解城市声景观要素之间的整体关系提供了实证依据，并表明场所功能应作为声景观设计的重要内容加以考虑。(C)2015 Elsevier B.V.版权所有。
This study aims to investigate relationships between soundscapes and landscapes within various functions of space, and to examine the influence of functional aspects of places on soundscape perceptions in urban environments. Surveys were conducted to assess soundscape and landscape perceptions in 25 locations in Seoul. Urban contexts were classified into four categories based on main functions, activities, and visual properties of the spaces: commercial, residential, business and recreational. A structural equation model of urban soundscape was constructed using seven factors, namely sound sources (traffic, human, and natural), pleasantness and eventfulness, visual quality, and the harmony of the environment. The model appropriately fit the data measured in the survey. The results showed that dominant factors affecting soundscapes differed in accordance with the main functions of the place. In commercial areas, sounds from human activities played a significant role in evaluating soundscapes. For residential and business functional areas, traffic noise was a dominant sound source influencing the soundscape quality. In addition, human sounds from leisure activities played an important role in constructing a relevant soundscape in urban recreational areas. The findings of this study provide an empirical evidence for understanding the holistic relationships among soundscape factors in urban contexts and demonstrate that functions of place should be taken into consideration as an important context for soundscape design.
