城市数据管理运行中心扩声系统设计

Design of sound reinforcement system for urban data management center

针对城市数据管理运行中心的席位方位复杂,拾音范围大等特点,文章给出了相应的扩声系统设计方案,并对系统的拾音部分、信号传输部分、信号处理部分和扩声部分进行简要介绍;文中提出本项目中扩声系统面临的关键问题和要点,并对应给出关键问题和要点的解决途径;最后,通过计算机仿真和实际测量结果证明,本扩声系统设计方案能够满足设计目标。

In view of the characteristics of urban data management center,such as complex seat orientation,large pickup range,etc.,this paper gives the corresponding sound reinforcement system design scheme,and briefly introduces the pickup part,signal transmission part,signal processing part and sound reinforcement part of the system.In this paper,the key problems and key points faced by the sound reinforcement system in this project are put forward,and the key problems and key points are correspondingly given Finally,through the computer simulation and the actual measurement results,it is proved that the design scheme of the sound reinforcement system can meet the design objectives.
