20100300801 | SOUNDPROOFING OR SOUND-ABSORBING MATERIAL - The described and claimed soundproofing material is planar and has an inhomogeneous structure. It consists of a textile or mesh having relatively thick, adjacent longitudinal components and relatively thin components running in the transverse direction at a spacing from one another. Longitudinal microslits are formed between the longitudinal components by the distribution of the thin transverse components. The width of the microslits amounts to 0.01 and 0.4 mm, and the thickness of the longitudinal components amounts to at least five to ten times that of the microslits. | 12-02-2010 |
