A panel (10) for sound suppression consists of a multiplicity of rigid elements (12) that extend parallel to each other, with gaps between adjacent rigid elements. Within each gap a vortex chamber (15) is defined to attenuate acoustic waves. The elements (12) may have curved edge portions (14), the edge portions (14) of adjacent elements (12) overlapping to define the vortex chamber (15), and also defining a first channel (16a) and a second channel (16b) communicating with the vortex chamber (15) at its periphery and aligned with a tangential component, such that if a fluid were to flow in through either channel (16a or 16b) the fluid would enter the vortex chamber (15) with a rotational sense relative to the vortex chamber (15), the rotational sense being the same for both the channels (16a, 16b). Such a sound-attenuating panel may for example be used as part of a wall of a loudspeaker housing (50).
A panel for sound suppression, the panel comprising a multiplicity of rigid elements that extend parallel to each other, with gaps between adjacent rigid elements, and within each gap a vortex chamber is defined to attenuate acoustic waves, wherein the rigid elements have curved edge portions, the edge portions of adjacent elements overlapping each other, the overlapping edge portions of adjacent elements defining between them the vortex chamber, and also defining a first channel and a second channel communicating with the vortex chamber at the periphery of the vortex chamber and aligned with a tangential component relative to the vortex chamber, such that if a fluid were to flow in through the first channel or in through the second channel the fluid would enter the vortex chamber with a rotational sense relative to the vortex chamber, the rotational sense being the same for the first channel and the second channel.
