摘要

The Invention is a structure Acoustic insulation Construction reflects the principle of mass - Spring - MassThe two masses of the system mass - Spring - Mass each comprise at least a rigid element (1,2) and are separated by the least mineral Wool Board (4) associated with at least one layer of Air (5).The Acoustic structure is such that the Rigid Elements (1,2) are u-shaped plates stuffed inside the u with at least a Mineral Wool (3).
