Investigation of the mechanism of noise radiation reduction from an ABH-cavity under interior acoustic excitation considering multistage coupling

•Investigation into the noise suppression mechanism of an ABH-cavity system under interior acoustic excitation.•Study of the acoustic radiation characteristics of ABH plates at lower frequencies.•Examination of the coupling mechanism between the acoustic space and the ABH plate.•Manipulation of the mapping matrix and variation in the number of ABHs to achieve reduced radiation efficiency of structural panels.
