In this paper, the reproduction of industrial or vehicle sound environments is investigated. The method relies on the combination of microphone array recording, beamforming, Wave Field Synthesis (WFS), and bass equalization. The approach is based on fixed looking-direction beamformers to separate signals depending on their incoming direction. The beamformer signals are then processed by WFS in order to recreate the sound environment as multiple plane waves. A theoretical parametric study based on the number of beamformer steering directions is provided. Comparisons of the target and reproduced sound environments are reported in order to identify appropriate system parameters for the reproduction of sound environments as found in vehicle or industrial contexts.
