Abstract
Propagation of vehicle interior noise may be discovered through experimental or analytical methods. This study demonstrates a new MATLAB™ application, where detailed acoustic distributions are determined and displayed from limited measurements. In particular, this method renders energy emanating from a commercial truck dash panel. Results show discernable surface details with a blanket contour plot. The contour mesh comprised of linearly-interpolated values from a small number of discrete measurements. Qualitative and quantitative conclusions were easily made from this interpolation, including relative acoustic leakage and radiation concerns - demonstrated by near-field sound intensity.
