| Abstract: | 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. |
