【摘要】This paper introduces the multi-channel noise test system based on virtual instrument technology. This test system uses microphones,preamplifier and sound vibration data acquisition hardware.The test sys-tem is realized by LabVIEW;it can test the sound pressure level and sound power level for machinery and oth-er machinery.And
the
test
system
with
high
performance,high
precision,etc.,greatly improving the efficiency while significantly reducing the cost of test.%该文介绍了基于虚拟仪器技术的多通道噪声测试系统。该系统硬件采用了传声器、预放及声音振动数据采集卡,通过LabVIEW编写测试系统,实现对机器机械等噪声源的声压级和声功率级测试。该测试系统具有高性能、高精度等优点,在提高效率的同时降低了测试成本。 【总页数】5页(44-48)
