在影视作品中 ,画外音应起到展示、塑造影片的画外空间 ,丰富镜头的信息量。画外音有多种表现形式 ,如来自画面外的声音、旁白、独白、解说等。有声电影中声音空间的重要性还应表现在画外空间对声音空间的倚重上 ,应确立正确的。

This negatively impacts the performance of underwater detection equipment. The properties of sound absorption in turbid water are not well understood. In this paper, the coefficient of sound absorption in turbid water was measured by the reverberation technique. All work was done in a reverberation barrel made of seamless aluminum. First, pure water was poured into the reverberation barrel and its reverberation time measured. Next, various concentrations of turbid water were poured into the barrel and their reverberation time measured. After all data had been gathered, the coefficient of sound absorption in turbid water of different concentrations was calculated. From this we determined a law of sound absorption in turbid water as summarized in the paper. 展开更多
