高大空间报告厅影音系统方案研究

Research on Scheme of Audio and Video System for Tall Space Lecture Hall

对于高大空间报告厅,为达到最佳的视听效果,在影音系统设计时须充分考虑声场覆盖的均匀度、可懂度,图像显示的完整性、清晰度,观众视听的舒适性等问题。对影响以上指标的因素进行研究,通过模拟、对比目前主流技术等选取最佳方案,最终提出了一个完整的高大空间报告厅的影音系统设计方案,对于此类空间的影音系统方案设计具有一定的参考价值。

For a tall space lecture hall,such parameters as the uniformity and intelligibility of sound field coverage,integrity and clarity of image display and audience’s audio-visual comfort should be taken into full consideration when designing the audio and video system of the hall.Thus,the factors that might affect those parameters are studied.Through simulation and comparison of current mainstream technologies,the optimum scheme is determined.Finally,a complete design of the audio and video system for tall space lecture hall is proposed,which has certain reference value for the design of the audio and video system for similar venues.
