SOUND-DAMPING PROFILED MEMBER

摘要

A strip to be inserted between two elements to cause acoustic attenuation of noise propagating through at least one of the two elements. The strip is made of at least one plastic-based damping material, the strip having an equivalent real stiffness per unit length K'_eq equal to at least 25 MPa and an equivalent loss factor tan delta_eq equal to at least 0.25.
