体育馆场地扩声系统设计研究

Study on Design of Sound Reinforcement System in Stadium

本文以第十四届全国运动会柔道比赛体育馆的声学设计为例,从建筑声学和电气扩声两个角度深入研究同类型体育馆声学系统并总结出声学指标、扩声要求、保障措施及模拟计算流程。在建筑声学方面,通过建立体育馆建筑声学设计流程,在对吸声材料进行充分研究的前提下合理选用和布置吸声材料消除声音缺陷,控制各项声音特性指标以保证听音效果。在建筑声学达到既定目标的前提下,采用计算机声学辅助设计软件EASE进行扩声系统的设计与模拟分析,从而保证系统设计和设备配置的合理性。通过设计经验总结出同类型体育馆声学设计的规律与要点,供体育馆设计者参考交流。

This paper examines the acoustic design of the judo competition gymnasium used in the 14th National Games as an example.It comprehensively studies the acoustic system of similar gymnasiums,considering architectural acoustics and electrical sound reinforcement.The paper summarizes the acoustic indicators,sound reinforcement requirements,safeguard measures,and simulation calculation process.Regarding architectural acoustics,the paper establishes a design process for the gymnasium.It involves conducting thorough research on sound-absorbing materials to select and arrange them reasonably,aiming to eliminate sound defects.Various sound characteristic indicators are controlled to ensure optimal listening effects.Once the established goals of architectural acoustics are achieved,the computer-aided design software EASE is utilized to design and simulate the sound reinforcement system,ensuring the rationality of system design and equipment configuration.The author summarizes the principles and key points of acoustic design for similar gymnasiums by drawing on design experience.This provides a valuable reference and facilitates knowledge exchange among gymnasium designers.
