摘　　要：噪声危害越来越受到各国政府和人们的关注,尤其是低频部分。声子晶体在弹性波范围内可以产生带隙的特点足可以应用到建筑隔声领域,从而使隔声性能提高且可人为控制其禁带范围。引入声子晶体理论到建筑隔声领域的研究,必将会对建筑隔声控制技术带来全新的设计思路和对传统经验公式及测试手段的严峻挑战。主要论叙了噪声的危害、传统建筑隔声的现状与不足、声子晶体的基本概念和特征、能提高低频隔声量的分析及应用前景。More and more government and people are concerned to noise damage, particularly low-frequency part. Characteristic, which phononic crystal can produce band-gap within the elastic wave, can be applied to the field of construction sound insulation. So that people can improve performance and control its band-gap range. Presented the theory of phononic crystal into the field of construction sound insulation, it will bring new design ideas to construction sound insulation control technology and tough challenges to traditionally experiential formula and the testing means. This paper mainly discuss noise hazards, the status quo and inadequate of the traditional sound insulation, the basic concepts and features of phononic crystal, the analysis of improving the transmission loss of the low frequency noise and its application.
