This paper addresses the active noise control of sound transmission loss of polymer film. It is well known that the sound transmission loss is dependent on mass of material. Then, because of its lightness in weight, polymer film is unsuitable for noise insulating material. Applying active cluster control method consisting of both cluster filtering and cluster actuation, we propose lightweight acoustic isolation system utilizing a polymer film. First, we investigate the correlation between the mechanical properties of materials and acoustic radiation characteristics. Next, an optimal feedforward control law for minimizing acoustic radiation power is derived. Under the optimal control, sound transmission loss of a simply supported polymer film embedded in an infinite baffle is calculated. Finally, the correlation between the mechanical properties of materials and the control effect applying active cluster control method is discussed.
