响度是评价剧场音质的重要指标之一，研究影响剧场响度的建筑因素对剧场音质设计有着重要意义。目前评价响度的客观参量是相对强感（G），确切的说是中频相对强感（Gmid）。通过skechup设计软件创建剧场三维模型，用声学模拟软件Odeon进行计算机模拟发现：随着舞台高度升高，观众厅Gmid值会出现明显的提高；随着观众席踏步高度的降低，观众厅Gmid值呈明显下降趋势；台口反射板的角度变化对观众厅Gmid值的影响比较显著，可使局部区域出现明显的上升或下降。

Loudness is a important indicator of theater sound quality evaluation.Architectural factors witch affect the Loudness are of great significance to theater acoustical design. Strength of sound (G) is the parameter of objective evaluation for Loudness.Strictly speaking,medium frequency sound strength (Gmid) is the parameter of objective evaluation for Loudness. Theater three-dimensional model was created by skechup design software. The conclusion by computer simulation is:with the stage height increases, Gmid appears significantly rised,with the auditorium stepping height reduction, Gmid showed a downward trend, the angle of the proscenium reflector has a significant impact on Gmid, with the proscenium reflector angle changing, Gmid of local region rises or falls.
