ABOUT ACCOUNT OF ACOUSTIC PERFORMANCES IN CABINS OF THE JIB CRANES, THE INTERNAL-COMBUSTION ENGINE STIPULATED BY IMPACT

Process of formation of acoustic performances in cabins of jib cranes in-process surveyed. Dependences of formation of noise in cabins from external sources of an aerodynamic noise are detected and on the basis of it possible ways of drop of levels of a sound pressure on workplaces of crane operators.
