摘要: The paper describes an array-based method for measurement of panel contributions in a cabin. Both the FRF measurements and operational are taken with dual layer microphone array, required sound field data on surface mesh calculated using SONAH patch holography algorithm. Multiple array positions can be measured to cover needed area, area-integration is then performed mesh. Measurement or alignment geometry integrated 3D position system. After theoretical description evaluated through simulated actual measurements.
