摘　　要：录音室,演播室等房间除了要求室内建声环境指标的数值及频响特性严格满足规范外,常采用扩散体等手段保证室内绝大部分区域的建声环境指标基本一致,以确保传声器能在任意位置高质量拾音。以新疆广电译制中心录音棚,西南大学录音室,重庆电大演播室为样本,在Odeon软件系统参数的设置中将扩散体与地面的散射系数按指定的序列取值进行计算,对计算结果与测量值间的差异进行讨论,最后对软件计算中散射系数的取值,软件用模型制作的精细程度的选取得出结论。In addition to the requirement of indoor acoustic environment index value and the frequency response characteris- tics to meet the code, energy acoustic diffusers are often used in studio room for the most part indoor area of architecture a- coustics environment indicators are basically identical. To ensure that the receiver can pick up high quality at any position, the studio room of Xinjiang Radio and Television Center , the Recording Studios of Southwest University, the Studio Room of Chongqing TV University are taken as samples, in the Odeon software system parameter setting, spread energy acoustic diffuser and the ground scattering coefficient according and calculated according to the specified sequence, the differences between the calculation results and the measured value are discussed, a result to the software of the scattering coefficient val- ues and model precision is given.
