摘　　要：在小空间听音半径2 m的条件下,通过对比无混响情况与4种不同混响情况下,5种类型的电影片段在临场感、包围感以及纵深感等7个听感指标的环绕声效果听音结果,分析小空间中混响对环绕声效果感知的影响。结果表明,混响对与空间有关的纵深感和空间舒适性有正面作用,而对其他的感知特性有一定的负面作用。With the condition of listening radius of 2 meters in small space,the surround sound quality of five types of film scenes was evaluated on the 7 sound attributes such as the presence,the envelopment,environment depth,et al.By comparing the subjective evaluation results of no reverberation and the different reverberation,it shows that the reverberation has a positive effect on attributes related to space such as environment depth but has a negative effect on other sound perceptual attributes such as the presence.

关 键 词：听音半径 混响 环绕声效果 主观感知
