Abstract

See full text

A building element includes a sheet of a rigid material and at least one nonlinear energy sink including a blade with two end parts and a nonlinear spring function intermediate part, a mass fixed to the nonlinear spring function intermediate part of the blade, and a fixing element allowing the two end parts of the blade to be fixed to a solid support in such a way that the nonlinear spring function intermediate part can oscillate about its position of equilibrium or its positions of equilibrium. The nonlinear energy sink is fixed rigidly to the sheet by the fixing element. The building element can be contained in a partition wall. Additionally, such an energy sink or building element can be used for reducing the acoustic transparency of a wall.
