Visualizing and finding exact noise source locations on the surface of a moving object is required for reducing noise. A two-dimensional microphone array with high resolution together with a visual sensor to acquire a picture of a moving source was developed. However, it's calculation performance is desired to be improved so that users can get result in relatively short time. Windows-based PC cluster management middleware, provided with parallel data distribution and task load balancing functions, has been developed. It enables easy transportation of Windows-based applications such as noise source analysis and indication application to PC clusters, and gives them high computational performance. Performance evaluating experiments of this system is conducted. The tests are conducted on PC cluster and grid computer. The parallelized efficiency was over 98% on the PC cluster and about 64% on the grid computer.
