Abstract：This article introduces an instrument for sound wave sampling which can be used in industry environments. The instrument is formed by IPC,exact sound level metre, data sampling card and software for sampling and analysis. The software uses DMA means to sample and transmit data, the realtime of data sampling under Windows operation system are guargnteed by use a circle buffer, multi-thread mechanism makes hardware exerts its fully faculty. Through practiced used in a waterpower station, it has been proved that this system has better ability of anti-jamming,it can be used in industry environments which has stronger jam.
