The microphone array phased processing system (MAPPS)

A measurement system has been developed to meet increasing demands for detailed noise measurement of individual model components. The Microphone Array Phased Processing System (MAPPS) incorporates a heterogeneous network of computers with a 40-element acoustic array and produces noise maps for selected frequencies in a near-real-time testing environment. This system has been used successfully on a model scale test in the NASA Ames 40by 80-Foot Wind Tunnel. (Author)
