This paper presents the results of experimental determination of sound transmission loss indices of a rectangular plate with energy-absorbing coating, which were obtained in the reverberation acoustic laboratory and intended to verify the data of theoretical studies. The proposed experimental methodology allowed to receive not only the average values of sound transmission loss indices of the plate placed between the high and low pressure chambers, but also the field of sound pressure distribution indices in the low pressure chamber. The results are compared with the similar ones for plates without coating.
Keywords: laminated plate, sound insulation, energy-absorbing coating, acoustic laboratory, sound pressure, experimental investigation.
