摘　　要：通过对爱达·魔都号邮轮剧场的声学测试,本文对其音质和缺陷进行了深入的分析,得到以下结论:(1)该剧场具有优异的语言清晰度效果,满足主要需求;(2)该剧场中频混响时间约为0.53 s,中频音乐明晰度C80为11.06 dB,相对音乐演出而言,音质有提升空间;(3)该剧场各测点的频带声压级标准偏差均小于10 dB,表明剧场内声场均匀度尚可;(4)利用ODEON软件进行了模拟,结果表明:剧场目前的室内装饰吸声过量,特别是吸声吊顶导致了混响时间过短,音乐明晰度过高。对于邮轮剧场这样的扁平空间,只要采取吸声地毯、座椅和局部吸声墙面,注重吊顶和部分墙面的扩散设计,就可以获得令人满意的音质。Through the acoustic test of the Adora Cruise theater,this paper provides an in-depth analysis of its sound quality and defects,and obtains the following conclusions:(1)the speech intelligibility of this theater is good and meets the main needs very well;(2)the mid-frequency reverberation time of this theater is about 0.53 s and the music clarity C80 is 11.06 dB,and compared to the musical performances,the sound quality still has room for improvement;(3)the standard deviation of the frequency band sound pressure level of each measurement point of the theater is less than 10 dB,indicating that the uniformity of the sound field in the theater is still available;(4)the simulation was carried out by using the software ODEON,and the results show that:the theater has the problem of excessive sound absorption in the indoor decorations,especially acoustic ceilings,leading to reverberation time and music clarity and other indicators are less than ideal.For a flat space like a cruise theater,satisfactory sound quality can be obtained by adopting acoustic carpets,seats and local acoustic walls,and focusing on the diffusion design of the ceiling and part of the walls.
