摘要
应用统计能量分析(Statistical Energy Analysis,简称SEA)理论对隔绝建筑楼板撞击噪声的机理进行探讨,通过建立相应的理论模型,对楼板的隔声能力进行计算,且与楼板隔声实测结果相符,这表明应用SEA建立的隔绝撞击噪声计算模型是可行的。
Statistical energy analysis ( SEA ) theory is employed in sound insulation research of a floor plate. The sound insulation of a floor is predicted by the SEA calculation model. The result shown that there is good agreement between experimental Value and predicted by SEA, and the SEA calculation model is feasible for calculating the impact noise of a floor plate.
