Abstract (en)
[origin: WO2004012952A2] Disclosed is a profiled member (3) to be inserted between two elements (1, 2) so as to dampen the noise spreading across at least one of the elements. Said profiled member (3) is made of at least one plastic-based damping material. The invention is characterized by the fact that the profiled member (3) has an equivalent real stiffness per unit length (K'eq) of at least 25 MPa and an equivalent loss factor (tandeq) of at least 0.25.
