摘　　要：对于宁波大学的体育馆的扩声系统的设计进行了详细的介绍。考虑到体育馆内部的空间大,混响时间长的建筑结构的缺陷。在吊顶上采用了大量的吸声体解决了混响时间过长的问题。同时,采用集中式的阵列扬声器的布局模式解决了声压级的覆盖以及对语言清晰度要求的矛盾。同时在系统中采用了大量的数字音频处理器设备简化了系统的结构,提高了系统的可靠性。In this article the design of sound reinforcement system for Ningbo University gymnasium are introduced in detail.Taking into account the stadium interior space,architectural structure defects long reverberation time. In the ceiling with a large number of sound absorbing body solves the problem of the reverberation time is too long. At the same time,using the array loudspeaker centralized layout mode to solve the contradiction,the sound pressure level of coverage and on speech intelligibility requirements. At the same time,the system adopts the digital audio processor device greatly simplified the structure of the system,improve the reliability of the system.
