A compressed air muffler comprises a rear attachment section, a compressed air muffler section adjoining it in the longitudinal direction with a compressed air muffler body of a porous compressed air muffler material and an outlet duct extending in the length direction as far as a front outlet opening, such outlet duct having in the muffler section, a form tapering toward the outlet opening. The muffler body has a bare outer peripheral face, its outer periphery face constituting an outlet face for the compressed air flowing through its wall athwart the longitudinal direction. The duct section extending through the attachment section, of the outlet duct merges steplessly with the duct section running in the muffler section.
