【摘要】 本文以青岛、北京等地的室内乐园噪声调研数据为基础,利用Odeon声学模拟软件对青岛室内主题乐园的SPL、SPL(A)、T30和语言传递指数进行模拟预测分析,发现存在噪声超标,为此进行了降噪声学设计。结果表明,通过对屋顶和侧墙合理布置吸声结构,能够有效的降低室内乐园内部游乐设施产生的巨大噪声,同时,此布置方式和设计方法对以后同类场馆的声环境降噪具有较大的参考价值。更多还原

【Abstract】 In order to obtain the relevant sound pressure level and sound power level data by making investigation and research of the similar indoor park in Beijing and Qingdao. By using the odeon acoustic simulation software to simulate and forecast SPL,SPL and T30( A) and language transfer index of the Qingdao indoor theme park and get the noise problem of acoustic exceed the standard,then to make the reasonable design of its acoustics. The results show that It can effectively reduce the huge noise of indoor amusement equipment by rational arrangement of the roof and side wall of sound absorption structure,meanwhile the arrangement and structure design method has have great reference value for the acoustic design which is the same kind of buildings in the future.更多还原
