摘　　要：由于大歌剧院风管系统产生的振动对声学影响较大,故在风管系统建设前对不同隔声材料进行配比后在实验室进行测试。发现5mm厚A品牌隔声毡+48kg/m^(3)容重、3cm厚离心棉保温的材料配比对中低频有较好的减噪作用,能很好地降低噪声对歌剧院的危害。此次测试可为后续声学要求较高的歌剧院或会议室等建筑的室内管道施工提供一定的选材方案和声学指导。Because the vibration produced by the air duct system of the Grand Opera House significantly impacts acoustics,different sound insulation materials were tested in the laboratory before the construction of the air duct system.It was found that the material ratio of 5 mm thick Brand-A sound insulation felt and 48 kg/m^(3)bulk density,combined with 3 cm thick centrifugal cotton insulation,has a good noise reduction effect on low and medium frequencies,effectively reducing noise harm to the opera house.This test provides material selection schemes and acoustic guidance for indoor pipeline construction in opera houses or conference rooms with high acoustic requirements.
