THERE IS DISCLOSED AN ACOUSTIC TILE FOR REDUCING VIBRATION AND SOUND IN A VEHICLE BODY PANEL SUCH AS THE ROOF, BONNET AND DOOR PANEL. THE ACOUSTIC TILE (1) COMPRISES A BASE LAYER (11) AND AN OUTER LAYER (12). IN PRACTICE, THE BASE LAYER (11) ACTS LIKE A SPRING AND THE OUTER LAYER (12) ACTS LIKE A DEAD WEIGHT AND VIBRATION IN, THE OUTER LAYER (12) WILL CANCEL VIBRATION IN THE VEHICLE BODY PANEL THUS MAKING THE VEHICLE SMOOTH AND COMFORTABLE.
