【摘要】 在研究声音及其监测的过程中,均需要专门的分析工具。吸收虚拟仪器概念,利用LabVIEW8.20新开发的多功能虚拟声信息分析仪,集时域、频域等多种分析功能为一体,尤其是在长时间声音的平均频谱分析方面有独到的功能。直观友好的界面,多样快速的分析处理成为该虚拟仪器的最大优势。它不仅会成为有关声学研究方面的基本工具,而且会在防盗报警、车检等相关的声音鉴别系统中有特殊的用处。更多还原

【Abstract】 Special analysis tools are all needed in the research about the sound and its monitor. Absorbing the concept of Virtual Instrument, the multifunctional virtual instrument for sound signal analysis developed in LabVIEW8.20 has variety of functions such as the time domain and frequency domain analysis etc, particularly the original function in sound average spectrum analysis for long time. The ultimate superiority of this system is its friendly user interface and diverse analysis in high speed. thus, it can not only become the basic tool in acoustics researches, but also has special use in sound distinction system such as the guard against theft and alarm system, vehicle monitor and so on.更多还原
