Experimental study of the effect of the design features of frame partitions on their sound insulation

摘要

This paper presents an experimental comparison of various multilayer frame-sheathing structures and describes the effect of their design features on their own sound insulation. The paper discusses the dependence of sound insulation on material and type of the frame, the amount and density of the filler, the number and type of facing layers, the presence of a damping layer and a divided base.
