Abstract

Sound absorber of slides for circulating gases in ventilation and air conditioning installations, with a tube-shaped channel, preferably rectangular or square in profile, respectively, which incorporates slides filled with absorption material that divide the channel into several current channels parallel to each other, characterized by the fact that the sliders (5) are open on one of the two sides opposite to the circulating gas and closed on the other side.
