High efficiency, frequency-tunable, acoustic wool and method of attenuating acoustic vibrations

摘要

A high-efficiency, frequency-tunable, acoustic wool, includes a multiplicity of randomly-arrayed, continuous fibers. The fibers have segments differing in at least one physical parameter for attenuating acoustic vibrations. A method of attenuating acoustic vibrations includes providing continuous fibers having segments differing in at least one physical parameter. A multiplicity of the fibers are randomly arrayed into an acoustic wool.
