非声学公共建筑中的声品质

本文分析了在八种公共建筑类型中的声学专题研究结果, 包括火车站、商城、图书馆、开敞式办公室、足球场、游泳空间、用餐空间、及教堂, 旨在考查主观评价和客观指标之间的关系, 并且探索在非声学建筑中创造舒适的声环境的原则和框架。分析表明了声品质在这类非声学建筑中的重要性, 另外, 即使客观指标例如声压级和混响时间相同, 声舒适度亦可能完全不同。其它关键因素包括社会背景、心理调节、声音喜好、声学处理的接受程度, 声学与其他环境因素的相互作用、以及不满意的声品质可能造成的健康影响。

Acoustic quality in non-acoustic public buildings

This paper analyses the case study results in eight types of public buildings, including railway stations, shopping malls, libraries, open plan offices, football stadia, swimming spaces,dining spaces, and churches, aiming at examining relationships between subjective and objective indices, as well as principles and framework for creating comfortable acoustic environments in such' non-acoustic' buildings. It is revealed that acoustic quality is an important consideration in these buildings, and it may vary considerably with the same objective acoustic indices such as sound pressure level and reverberation time. Key factors to be considered include social demographic background, psychological adaptation, sound preference, preference of acoustic treatments, interactions between acoustic and other environmental factors, and possible health effects of unsatisfactory acoustic quality.
