Abstract
L'invention concerne une feuille d'amortissement à adhérence magnétique possédant des propriétés d'amortissement améliorées et d'une faible teneur en ferrite ainsi que le procédé pour sa préparation. La masse magnétique (1) est dans ce cas introduite dans des bandes sur un côté de la surface de la couche de la masse d'amortissement (2). La totalité de la masse magnétique est magnétisée, contrairement à la feuille connue à deux couches.
