学术报告厅建筑声学环境细部设计

Study on Detail Design of Architectural Acoustics Environment in Academic Lecture Hall

从湖南省博物馆学术报告厅的建筑声学环境功能需求出发,根据学术报告厅体型和指标确定目标,针对不同的功能与指标选择适宜的装修饰面材料,进行声学细部构造设计,从而确保学术报告厅的良好音质.建立三维模型计算各项声学指标,模拟声场覆盖与声压级不均匀度,优化设计与施工方案,保证学术报告厅的声音质量.项目竣工后,进行声学检测,结果表明各项指标合理,均在优选范围之类,达到博物馆学术报告厅使用的声学目标.

Based on the requirement of the building sound environment function of the academic report hall of Hunan Province Museum this paper determines the target according to the figure and index of the academic report hall,it selects suitable decoration finishing materials for different functions and indexes,and the designs the acoustic detail structure,thus it is ensuring the sound quality of the academic report hall.The three-dimensional model is established to calculate the acoustic parameters,to simulate the inhomogeneous degree of the sound field coverage and sound pressure level,to ensure the sound quality of the academic report hall,and to optimize the design and construction scheme.After the project was completed,the acoustic detection was carried out.The results showed that all the indexes were reasonable,all in the range of optimization and so on,it is to achieve the acoustic targets used by the museum's academic report hall.
