摘　　要：为满足北京艺术中心公共空间的严格声学标准,特别选择了玻璃丝棉作为开放式吊顶区域的吸音体材料。通过采用离心玻璃棉外包玻璃丝布的结构形式,确保了吸音效果的持久稳定性。在施工过程中,我们从材料的选择到每一个施工步骤都实施了严格的控制,以保障吸音体结构的卓越质量。最后,通过传递函数法的声学测量,验证了吸音体在中高频段表现出色,但同时也意识到在低频段仍有提升的空间。通过深入的施工设计和严格的质量控制,北京艺术中心的玻璃丝棉吸音体成功取得了显著的吸声效果,为公共空间提供了一流的声学解决方案。In order to meet the strict acoustic standards for the public space of the Beijing Art Center,glass wool is specially selected as the sound absorber material for the open ceiling area.By using a structure of centrifugal glass wool wrapped in glass wool cloth,the durability of the sound absorption effect was ensured.During the construction process,we implemented strict control from material selection to every construction step to ensure the excellent quality of the sound absorber structure.Finally,through acoustic measurement using transfer function method,it was verified that the sound absorber performed well in the mid-high frequency range,but it was also realized that there was still room for improvement in the low frequency range.Through in-depth construction design and strict quality control,the glass wool sound absorber of the Beijing Art Center successfully achieved significant sound absorption effect,providing a first-class acoustic solution for public space.
