Abstract
A method for reduction of noise from vibratory apparatuses for the compaction of concrete mixtures consists in placement of those in special pits that act as screens for acoustic energy. The compaction of concrete mixtures is carried out by means of a vibro-platform with fixed upper platform and movable lower one that are movably connected to each other with metal rods that are placed coaxially with the openings in the bottom of the mold for concrete mixture.
