船载游乐园建筑室内声环境设计

Interior Acoustic Environment Design of Ship-borne Amusement Park Building

目的为降低船载游乐园建筑室内混响时间,满足噪声限值的要求,制定声环境设计方案;选择符合游览空间适宜性的吸声材料,为游客提供良好的游览体验。方法以船载游乐园中"与金尼交战"的场景空间为例,分析船载游乐园室内空间的原设计方案;采用依林-努特生公式计算空间内混响时间与吸声量,通过分析吸声材料的声学特性与施工工艺,选用3种吸声材料配合的声环境设计方案;最终使用ODEON软件模拟验证设计方案的有效性。结果无机纤维喷涂材料,金属微穿孔板和薄板式共振吸声体的声环境设计方案,使空间内各频率吸声量达到设计目标,软件模拟空间内整体混响时间、游览路线声场均匀度与混响时间均达到了设计目标;经过声环境设计后该空间声环境明显改善,与原设计相比降噪量达到3 dB,各频率混响时间达到标准控制范围。结论采用合理的声环境的设计方案可以提升音质、控制噪声,使游览空间声环境满足正常使用需求。

In order to reduce the reverberation time of the ship-borne amusement park building and meet the requirements of noise limit,the sound environment design scheme is formulated.Sound-absorbing materials that are suitable for sightseeing space are chosen to provide tourists with a good sightseeing experience.Taking the scene space of"Battle with Ginny"in the boat amusement park as an example,the original design scheme of its interior space was analyzed.The reverberation time and sound absorption in space were calculated by Eyring-Knudsen formula.After analyzing the acoustic characteristics and construction technology of materials,a sound environment design scheme with three sound absorption materials is put forward,the effectiveness of this scheme is verified by ODEON software simulation.The sound absorption of each frequency in the space in the sound environment design scheme with inorganic fiber spraying material,metal microperforated plate and thin plate resonant sound absorber can reach the design goal.The entile reverberation time in the simulated space,sound field uniformity and reverberation time in the simulated tour route all reach the design goal.After the sound environment design,the sound environment of this space is obviously improved.Compared with the original design,the noise reduction reaches 3 dB,and the reverberation time of each frequency reaches the standard control range.Adopting a reasonable sound environment design scheme can improve the sound quality and control the noise,so that the sound environment of tourist space can meet the normal use requirements.
