Panel Contribution Analysis in a Vehicle Cabin using a Dual Layer Handheld Array with Integrated Position Measurement

Standard Details

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