Research output: PatentPatent


In the present disclosure is proposed a novel sound attenuating element for, at least in part, providing adequate or preferably improved sound attenuating properties without excessively impeding flow while being susceptible to automated or machine assisted manufacturing or for providing the public with a useful alternative. The novel sound attenuating element (120, 130) is formed at least in part by an assembly of a plurality of components (123, 124, 133) which are successively connected to each other, which each exhibit a curved shape, and which form at least one non-planar ruled surface (121, 131) when assembled.
