Abstract
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 is formed at least in part by an assembly of a plurality of components which are successively connected to each other, which each exhibit a curved shape, and which form at least one non-planar ruled surface when assembled.
Claims19
A sound attenuating element, which is formed at least in part by an assembly of a plurality of components, which:
- are successively connected to each other along a first axis,
- each exhibit an elongated shape such that a dimension of elongation extends perpendicularly to the first axis thereby forming an axis of elongation,
- are each bent along the axis of elongation to exhibit a curved shape, and which
- form at least one non-planar ruled surface when assembled, wherein every second component in the assembly extends in a non-straight angle, in respect to the successive component, wherein the components are elongated plates that are successively layered in the assembly,
- wherein the components comprise interlocking shapes to form a cross-wise subassembly of two interlocking components.

An enclosure for a sound attenuator, comprising:
- several spiral guides, which are configured to receive a plurality of components in a successively layered fashion so as to create at least one non-planar ruled surface for contacting a gaseous current,
- a first set of mutually opposing guides comprising a first and second guide, each guide configured to receive a respective opposing end of an elongated component to extend between the guides, and
- a second set of mutually opposing guides comprising a third and fourth guide, each guide configured to receive a respective opposing end of an elongated component to extend between the guides,
- wherein the two sets of opposing guides are angularly offset from each other about a first axis, wherein the two sets of opposing guides are configured to receive cross-wise subassemblies of two components along a first axis as a sound attenuating element covering an inner space defined by the enclosure when viewed along the first axis.
