Abstract

A noise test technology was proposed based on MIMO control strategy for direct acoustic field, comparing the acoustic field uniformity in different speaker array shapes, analyzing and comparing the acceleration response difference under reverberation field excitation. The study results show that the elliptical speaker array is more suitable for the direct acoustic field test. Compared with the reverberation field, the direct acoustic field based on this array has standing waves in the low and middle frequency bands. For the test parts subjected to different noise environments in different areas, distributed loading can be achieved through the direct field acoustic test technology based on MIMO control.
