城市开放空间的物质环境和社会环境影响着人们的行为和对城市的感知。声景观是城市开放空间的重要组成部分，良好的声景观的描述、评价和设计是产生良好声景观的关键环节。在这项研究中，正在开发一个用于城市开放空间声景观评价的人工智能系统。该系统考虑了声学因素，包括声源的级别、类型和频谱以及城市空间的反射效果；使用者的社会和人口因素；以及其他物理和环境因素，包括城市形态、小气候条件、热和视觉舒适性。自2001年以来，在英国、瑞士、意大利、希腊、德国和中国等国开展了一项大规模的社会调查。建立了适合于人工神经网络(ANN)建模的数据库。人工神经网络模拟生物大脑，是生物进化的简化模型。
The physical and social environments of open spaces in a city influence people’s behavior as well as their perception of the city. Soundscape is an important component of an open urban space, and key aspects for producing a good soundscape include its description, evaluation, and design. In this research, an artificial intelligent system is being developed for the analysis of soundscape evaluation in urban open spaces. The system considers acoustic factors including the level, type and spectrum of sound sources and the reflection effects of an urban space; users social and demographic factors; and other physical and environmental factors including urban morphology, microclimate conditions, and thermal and visual comfort. Since 2001 a large scale social survey has been carried out in England, Switzerland, Italy, Greece, Germany and China. Correspondingly, a database suitable for artificial neural networks (ANN) modeling has been established. Simulating biological brains, ANN are simplified models of the ce...
