基于网络技术的体育场庆典活动扩声系统设计

Designing on Amplifying System in the Stadium Celebration Based on Network Transmission Technology

体育场庆典活动主要是指各类运动会的开幕、闭幕仪式以及同时举行的大型文艺体育表演。讨论了此类活动对扩声系统的特殊要求及其设计特点,举出第九届全运会、第十届全运会、雅典奥运会等开幕式的大型庆典活动,分别采用集中供声、棚顶悬挂分散供声和沿跑道设置分散供声等不同布局的扩声系统工程实例,并进行了一些对比探讨。总结出沿环形跑道分散供声并采用数字网络传输的系统设计,以其良好的效果正逐渐成为大型体育场庆典活动扩声系统的主流方案之一。

The opening and closing ceremonies of many kinds of sports meeting and the incidental large scale literature art and sports performance are included in the stadium celebration. The special requirement of the amplifying systems and the designing characteristics are discussed. The engineering examples with different patterns are given for the centralized acoustic, overhead hanging diffusion acoustic and diffusion acoustic along the racetrack in the opening ceremonies of the 9th and 10th national sports meeting and Athens Olympic Games and there are some contrasts. Finally, the inclusion is deduced that the system designing employing racetrack diffusion digital network transmission is becoming one of the main streams of a fluid because of its good effect.
