中文摘要:
      一种具有大影像、360度水平视野、接近于全方位的立体声效果,以高保真的声画环境将观众包围,使观众产生强烈临场感的全周影院在国际上也为数不多,而在我国建造更是一种新的尝试.本文通过介绍北京长城全局影院的音质设计和声学性能的测试说明,虽然这种新形式电影系统与常现电影有明显区别,具有很多特殊要求,但通过建筑、声学、光学设计者的共同努力及密切配合,最终获得了视听性能满意的结果,使影院达到了国际先进水平,也为全周影院的再次建造和进一步提高提供了科学依据.
英文摘要:
      A circle vision theatre is a theatre which can provide audience with a big picture around horizontal field of vision, an almost omnibearing stereo sound effect, hi-fi sound and image, strong on-the-scene feeling. The construction of such kind of theatre in China is really a trial for the number of such theatres is limited in the world. This article presents the acoustic design and the measurement of the resulting acoustical properties of the Great Wall Circle Vision Theatre of Beijing.In so doing, It is found that although the new movie system has very special demands compared with the traditional, satisfactory audio-visual effect has been achieved through the joint effort and the close cooperation of architects, acousticians and opticists. The effort and cooperation enabled the cinema to come up to an advanced standards and may provide scientiftc basis for future construction and improvement of Circle Vision Theatre.
