Abstract

The present invention relates to a sound-absorbing channel element for a flowing medium. The channel element (1) has an inlet (2) connected to a sound source and an outlet (3), and is defined by outer walls (4) extending in the flow direction. In order to achieve simplified construction of sound-absorbers in a gas outlet channel, as well as greater efficiency and lower resistance, the channel element (1) in accordance with the invention is provided with partition walls (5, 6) running in the direction of flow. These divide the channel element (1) into several part-channels (7). Each part-channel (7) is provided with sound-absorbing members (8). The channels are of different lengths. The invention also relates to a set of channel element modules for modularised construction of such a channel element, and also a gas outlet channel where equivalent principles are applied. Finally, the invention relates to a method of manufacturing such a channel element, wherein this is composed of a set of channel element modules, and a method of suppressing the sound in a gas outlet channel wherein the channels are divided into part-channels in corresponding manner.
