[ What is claimed is:] [1.]1. A gas guide element with sound-absorbent walls for blocking or damping noise spreading into main conduits of a sound emitting machine, the gas guide element comprising a guide element body including a flexible sound absorbent inner hose resistant to mechanical, chemical and caloric load exerted by a gas to be guided; an outer hose; and a soft and flexible sound-absorbent intermediate layer of material disposed between said sound-absorbent inner and outer hose, said inner hose being composed of a flexible material and having an outer side provided with oscillating weighted metal elements which adsorb sound intensity, said sound adsorbent intermediate layer being composed of a randomly oriented pile of material into which said weighted metal elements are introduced, and said guide element body having a gas inlet and a gas outlet and at least one 360.degree. convolution between said gas inlet and said gas outlet.
