The present invention relates to an arrangement (1) for achieving a sound- damping absorbent effect in structures containing car stereo loudspeakers. A visco-elastic polymer (2) exhibiting an adhesive function is applied by spraying, brushing, rolling or spreading between two sheet-formed elements (3, 4) to form a composite sheet which, through the absorbent effect of the visco- elastic polymer on the resulting sandwich structure when the damping layer is subjected to shear deformation during oscillation, brings about a reduction in unwanted vibrations, resonances and reverberations in the structure formed by the sheet. The invention also relates to a method for manufacturing the arrangement.

La présente invention concerne un agencement (1) permettant de produire un effet d'atténuation sonore dans des structures contenant des haut-parleurs stéréophoniques d'automobiles. L'invention consiste à appliquer, par pulvérisation, enduction au pinceau, au rouleau ou au couteau entre deux éléments en forme de feuille (3, 4) un polymère viscoélastique (2) présentant des propriétés adhésives, de façon à former une feuille composite. L'effet atténuateur du polymère viscoélastique de la structure sandwich résultante fait que, lorsque la couche atténuatrice est soumise pendant une oscillation à une déformation en cisaillement, cette couche arrive à réduire les phénomènes vibratoires, de résonance et de réverbération indésirables dans la structure que constitue la feuille. L'invention concerne également un procédé de réalisation de cet agencement.
