摘要
使用NOR-840对会议厅内的21个点测量6个倍频带的声压级。会议厅模型中的座椅采用三种方式表达,分别用Odeon软件计算得到三组数据。对实测值与计算值采用分布曲线、等值线平面图方式表达室内声场,比对它们的差异并提出评价意见供使用者参考。
The sound pressure level by 6octave band of the 21 points in the meeting hall by NOR -840 is measured, and the sound field distribution with 3 kinds of seat models by the software of Odeon is calculated, then use sound field distribu- tion curve and sound field contour plane to express the interior sound field of the calculated and measured value, compare the differences and provide reference to the users.
