VIBRATION ISOLATION TREATMENT FOR PANEL

摘要

A vibration-proof treating method of a panel comprises moulding a loft nonwooven fabric (1) to become a cubic vibrationproof material of a concavo-convex shape having a convex part (2) and a flat part (3), directly binding the flat part to the one side or both sides of the panel (5), and forming a cubic air layer (6) between the convex part and the panel. The value of air flow resistance at the convex part is 30-300 c.g.s rayls. The method gives good sound-proofing and vibration-proofing effets.
