中文摘要：

大型综合商场的声环境非常重要。本文在对一个典型商场调查与测量的基础上,首先分析了集中式、区域式和自主式几类商业营销声源对商场内声环境的影响情况,结果表明集中式声源的影响面积最大,而区域式声源影响距离最远。在研究营销声对背景声的掩蔽作用时发现,集中式声源在0~8m范围内对背景音乐声有掩蔽作用,而区域式声源在0~12m范围内对背景音乐声有掩蔽作用。在这些声源对顾客的声舒适度的影响方面,距离集中式声源6~10m的范围内使用者的声舒适度最高,而对于区域式声源,使用者声舒适度较高的位置在0~4m的范围内。以上研究对如何有效布置声源以达到较好的营销作用提供了参考依据。

英文摘要：

Sound environment in shopping malls is very important. Based on questionnaire survey and field measurements for a typical shopping mall, some typical marketing sound sources are given in this paper, such as centralized types, regional types and shop types. On the sound field, the inf luence area of centralized type sound source is greatest, and the inf luence distance of regional type is farthest. On the masking effect, the PA system can be masked by the centralized type sound source at 0-8m, while it can be masked by the regional type sound source at 0-12 m. On the evaluation of acoustic comfor t, users have better acoustic comfort at 6-10 m distance from centralized type sound source, while users have better acoustic comfort at 0-4m distance from the regional type sound source. From this study, the marketing sound sources can be better arranged for users’ acoustic comfort.
