The chambers can be cylindrical or rectangular and should be arranged parallel to flow or alternatively offset to one another crossways. The openings (4) of the chambers lie on the impact face of the link. One or more of the soundproof seals (13) of the chambers should be adjustable lengthways and possibly activated. The intervals between the covering (15) and the chambers should be packed with fibrous or porous insulating material. USE - Heating and air-conditioning systems, soundproofing. ADVANTAGE - The link has resonator chambers inside closed off one end and variable in length with fiber or porous packing and end caps, the chambers flow-parallel or offset to damp down all frequencies, especially low frequency noise. The cylindrical chambers offer comprehensive sound damping and fit plant to suit.
