ABSTRACT:
In order to reduce static and dynamic pressures in pipelines or tubes and, in particular, in order to attenuate the transmission of sound through tubes in a longitudinal direction it is proposed to provide an outer member and/or an inner member of the tube in such a way as to afford elastic yieldability. Such an elastically yieldable outer member may, for example, be constituted by a low-wave, soft, radially breathing compensator or a corrugated tube. An elastically yieldable inner member may, for example, be constituted by an imperforate breathing body disposed within the tube.
