Abstract

Improvements in silencing devices and acoustic wave deformers, designed to dampen the suction or exhaust noise of a gaseous current, in the orifice of a pipe in which this current is the point or center of pulsations of sound or infra-sound frequency , characterized in that in the gas pipeline, as close as possible to the pulsation generating apparatus and in any case according to a length of the tube lower than the critical length at which the noises are generated, an apparatus is inserted that modifies the shape of the the wave in the sense of an increase in the duration of the periods during which, in the course of a cycle, the pressure increases in such a way that beyond this apparatus, the modified wave can reach the end of the pipeline without a rigid front is formed.
