摘　　要：对西安市某乙级体育馆现有场馆扩声问题提出改造方案。通过对其建声与电声的改造,对体育馆吊顶、墙面和地面等选择适当的吸声材料和构造及面积,计算各界面的吸声量和总吸声量,使混响时间满足设计标准。EASE软件通过建筑3D模型。运算分析体育馆内声学参量。达到体育场扩声系统一级指标,并满足第十四届全国运动会组委会要求。A retrofit plan was proposed to amplify the existing sound systems of Class B gymnasiums in Xi'an.Through the reconstruction of its architectural acoustics and electro-acoustics.Select soundabsorbing materials,structures and areas for the ceiling,walls and floors of the stadium.,calculate the sound absorption and total sound absorption of all aspects to make the reverberation time meet the design standards.EASE software uses 3D models of building to computationally analyze acoustic parameters in the stadium.It was able to reach the first grade standard of sound reinforcement system of the stadium,and meet the requirements of the committee of the 14th National Games of the People’s Republic of China.
