Abstract : The patent discloses a sandwich-type, electro-mechanical, absorbing, acoustic material, in a flexible sheet form, which comprises a thin sheet of elastomeric material within which are embedded particles having a size barely greater than the thickness of the elastomeric material. The particles may be of a transducer material, generally single-crystal, and/or of a resistive material. Two conductive sheets, one on each side of the elastomeric material, which make contact with the embedded particles complete the sandwich.
