会议系统的音响设计

Design of Conference Acoustics System

本文从实际运用中可能遇到问题的角度分析了会议音响系统的设计,根据会议音响系统中的信号流程阐述了音源部分话筒类型的选择,从多个方面对比了手拉手话筒和独立式鹅颈会议话筒的优、缺点。并详细介绍了音频信号的传输处理及转发,其中包括模拟传输与网络音频传输的对比,网络音频传输的CobraNet形式。根据实例描述了网络音频传输的应用,最后从音箱选型的角度分析了常见会议室的声音还原问题。

This paper presents some points for the design of sound system regarding practical application. Comparing the advantages between ＂hand in hand microphone ＂and ＂ gooseneck microphone＂, it describes the method to choose microphone at source side according to the sound signal procedure. In detail, it presents the processing, transferring of the sound signal, including comparing between analogue signal and network audio. Another method for network audio transferring called CobraNet is introduced in a practical case. At last, we analyze matters of audio reduction for speaker selection used in meeting room.
