SOUND-PROOFING PANEL WITH MAXIMAL SOUND-PROOFING PROPERTY Russian patent published in 1997 - IPC

FIELD: mechanical engineering. SUBSTANCE: panel has integral hermetic body 1 made of fluoroplastic material in which sealed is reinforcement 2 with internal space 3 having minimal distance between walls d, where medium vacuum is ensured with provision of condition l ≥ d, where l-length of free travel of molecules. Body 1 externally has sound-absorbing interlayers 4 at face side and interlayers 5 at rear side. Installed inside body 1 and bearing constructions 6 of structure on which body is fastened are magnets 7 with parameters such as polarity and magnetic field strength are so selected that there is no direct mechanical contact between body 1 and bearing constructions 6 and interval 8 is formed between them filled with air. Body reinforcement 2 is used as part of contactless fastening unit as winding of electromagnet 7 included in body and that is in certain places of panel body 1, its structural components 2, 7 are combined into one component (matched). EFFECT: high efficiency. 2 cl, 1 dwg
