本文采用ODEON计算机仿真计算和DIRAC建筑声学软件现场测量的方法,对两个结构相似、音质差异显著的多功能体育馆A、B实例中影响音质的关键参数混响时间进行对比分析,发现混响时间曲线中频段凸起是决定两体育馆音质优劣的关键,并将此结果作为B体育馆音质改造方案设计依据,经仿真证明该方案可有效的克服B体育馆的音质缺陷,达到与A体育馆相近的音质水平,本文所得结果对解决同类体育馆音质控制具有一定的参考价值和指导意义。
In this paper, ODEON computer simulation and DIRAC building acoustic software on-site measurement methods were used to compare and analyze the two key reverberation time parameters of sound quality in two multi-function stadium A and B with similar sound quality. It is found that reverberation time The convexity of the mid-frequency band in the curve is the key to determine the sound quality of the two gymnasiums. Based on this result, the results are used as the basis for the design of the B gymnasium sound quality modification program. The simulation proves that the solution can effectively overcome the sound quality defects of Gymnasium B and achieve similar sound quality to A Gymnasium Level, the results obtained in this paper have certain reference value and guiding significance for solving the sound quality control of similar stadiums.
