Abstract. esults of of the experimental study of sound insulation the vibrodamping elements with the changed flexural rigidity are presented in article. Influence of depth of cuts in elements on the frequency characteristic of sound insulation and the index of isolation of air noise of a protection is shown.
Key words: sound insulation, a vibrodamping element, the flexural rigidity.
