There is a problem of protection from high-level sound of city residents, employees of enterprises; to a greater extent, in the workshops of machine-building factories, for example, during stamping, forging and other metalworking processes. Specialists and maintenance personnel are exposed to high-intensity noise near powerful agitators, pumps, engines and other power equipment. Due to these circumstances, it is necessary to constantly improve systems, devices, materials, coatings that reduce the negative impact of high noise levels on people. For this purpose, various soundproof walls, panels, screens, plates are being developed. One of the directions of modernizing sound-proofing fences is the method of using vacuum to design these protective devices. The article discusses the use of vacuum in special sound-insulating panels developed by the authors. The information about bench experimental studies of some sound-proofing materials is given, some results of testing of vacuum sound-proofing panels are presented. The research stand and research methodology are described. The features of the stand for the study of sound-proofing properties of flat samples of sound-proofing materials of the same size and thickness are given.
