摘　　要：基于互谱声强测量的基本原理，设计并研制了一台便携式互谱声强测量仪器。该仪器以ＭＣＳ－５１系列单片机作ＣＰＵ，具有体积小、重量轻、功能多、造价低等一系列优点。通过对比实验验证，本系统可满足一般工程测试需要，具有很强的实用性。In this paper,the principle of measuring sound intensity by Cross Spectral method is discussed. A portable instrument based on this method has been developed. It uses MCS-51 series single-chip micro-processor as it's CPU with aseries of advantages such as small size,light weight,multiple fuction and low cost etc.By comparative experiments,it's tested and verified that thisinstrument isvery practical and can meet the needs of general engineering's measuring and analysing.
