基于计算机声学模拟的会场环境声场仿真系统研究

Research on Simulation System of Environment Sound Field in Conference Venue Based on Computer Acoustic Simulation

目前,我国各类会场数量日益增多,且拥有配备齐全、性能优良的扩声系统设备。但是,由于许多会场在前期建设过程中未严格按照有关标准进行声场设计,且在后期使用过程中维护人员缺乏专业知识来发现和改善声场问题,导致声场问题严重影响现场的会议效果,给各类会场的保障工作带来了困扰。为了方便、快速掌握房间声学特性,开展会场扩声系统声场分布仿真技术研究,开发了一款适用于会场保障的一般用户的仿真软件系统,解决了实际会场声场调整的难题。

At present,the number of various conference venues in our country is increasing day by day,and conference venues are fully equipped with sound reinforcement system equipment with excellent performance.However,because many venues did not strictly follow relevant standards for sound field design during the preliminary construction process,maintenance personnel lacked professional knowledge to discover and improve sound field problems during the later use process,which seriously affected the on-site meeting effect and provided guarantee work for various venues.In order to more conveniently and quickly grasp the acoustic characteristics of the room,this paper has carried out the research on the sound field distribution simulation technology of the sound reinforcement system of the venue,and developed a simulation software system suitable for general users of the venue guarantee to solve the problem of adjusting the sound field of the actual venue.
