摘要
会议室扩声是根据厅堂使用功能的要求来确定声压级等指标,进而设计扩声系统的,指的是建声分析和电声分析问题。对于会议室来说,先从建筑声学的参数作分析,求出声学特性。再从会议室的建筑声学特性,及会议室要求参数推导出对会议室电声系统的要求。
The conference room amplified sound bases on the functional requirements of the hal to determine the indicators of sound pressure level, and then design the amplified sound system, referring to the problems of construction sound analysis and electroacoustic analysis. As the conference room, people first analysis of the parameters of architectural acoustics to obtain the acoustic characteristics. Then from the meeting room features architectural acoustics and the request parameters of conference room to derive the requirements of conference room acoustic system.
