In determining the effective ways of reducing the vibration and noise of machinery, it is important to know the exciting sources which cause vibration and noise at each part of their structure and the various transmission paths to it. The sound intensity measurement was introduced to identify the sound sources in a machine structure and sound energy flow in the propagating space. This technique has become popular as a skillfull means of machine noise control. While the method of measuring vibration intensity to find the exciting sources and its application to a machine structure is still unsatisfactory. In this paper, an attempt has been made to measure the vibration intensity vector generated by an impulsive force on a rectangular steel plate being subjected to background vibration. The requirements for a practical method of obtaining an accurate vibration intensity measurement were also discussed.
