摘要：

This engineering report describes the application of the Spatial Decomposition Method in a car cabin using a compact microphone array. The proposed method provides objective analyses of the sound field with respect to direction and energy, and enables the synthesis for multichannel loudspeaker reproduction. Due to the acoustic complexity of a car cabin, a number of recommended steps is presented to improve both objective and perceptual performance of the method. The results suggest that the method can be successfully applied to car audio systems.
