Abstract
An acoustic damping material that includes at least one resilient sheet, wherein each of the sheets have a first side and a second side, and wherein at least two portions of the sides face each other to form a multi-layered structure, is provided. The resilient sheet may be made from any resilient polymer film, such as a polyolefin, and especially polyethylene. Also provided is an acoustic speaker system that has an exceptionally flat frequency response, especially at low audible frequencies. The system includes an enclosure, a speaker mounted to the enclosure, and acoustic damping material (according to this invention) inside the enclosure. An acoustic damping panel, which includes a frame and acoustic damping material fixed to the frame, is also provided.
