摘　　要：介绍了虚拟仪器的概念和功能,论述了虚拟仪器在声音信号采集及分析系统中的应用和意义,提出了构建虚拟仪器代替传统仪器的设计方案和硬件配置,最后通过分析虚拟仪器能够实现的声信号去噪及修正等控制功能,揭示了基于LabVIEW的虚拟仪器技术的先进性和合理性.This paper introduces the virtual acoustic system based on the LabVIEW, discusses the virtual instruments in voice signal acquisition and analysis system of application and significance, and puts for- ward the construction based on virtual instrument instead of traditional instrument design scheme and hardware configuration. Finally the acoustic signal denoising and correction function the virtual instrument can reulize, the advancess and retionality of the virtual instrument based in LabVIEW are proved by ana- lyzing.
