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。 The sound environment of a large shopping mall is very important. Based on the survey and measurement of a typical shopping mall, this paper first analyzes the influence of centralized, regional and autonomous commercial sound sources on the sound environment in the shopping mall. The results show that the centralized sound source has the largest impact area, However, the influence of regional sound source is the farthest. When studying the masking effect of marketing sound on the background sound, it is found that the centralized sound source masks the background music in the range of 0 ~ 8m while the regional sound source masks the background sound in the range of 0 ~ 12m. In terms of the influence of these sound sources on the sound comfort of customers, the sound comfort level of the user is the highest within 6-10m from the centralized sound source, and the region of high sound comfort level of the regional sound source is 0 ~ 4m range. The above research provides a reference for how to effectively arrange the sound source to achieve a better marketing effect.
