A device for vibro-acoustic insulation of object has placed in earth near source of vibration and noise vibro-protective screen made of protective material wave resistance of which is 1015 times, and surface density is 1.52.0 times larger that respective parameters of surrounding earth, and elastic-viscous pad placed under it. For damping of all reflected from screen acoustic energy, surface of fibro-protective screen is made at side of source of vibration concave, with surface curvature not lower than second order, and the pad goes to the same side by value not smaller than width of the basis of the screen. |
