    摘要: Aspects described herein relate metallic railings that include a sound damping polymeric material affixed to a surface of the railing. The metallic railing can be solid or hollow and can have a circular or non-circular cross section. By positioning the sound damping polymeric material on the inner surface or the underside surface of the metallic railing, the tone produced when the metallic railing is struck can be tuned.
