description The utility model relates to a runner noise damping means, including air pipe (1) and well low frequency chamber pipe sound absorbing structure (4), wherein air pipe (1) inboard wall coupling has welllow frequency chamber pipe sound absorbing structure (4), well low frequency chamber pipe sound absorbing structure (4) is inside to form a plurality of sound absorption monomers (2) through divisionboard (5), the inside cavity structure that is of sound absorption monomer (2), sound absorption monomer (2), well low frequency chamber pipe sound absorbing structure (4) homonymy be equipped with the hole, and hole frontage and airiness pipeline (1) inboard for installation long tube (3), install in the cavity of sound absorption monomer (2) long tube (3). The utility model discloses simple structure can adjust the mouth of pipe, length waits the resonance coupling frequency of adjusting the cavity for air pipe's wall has fine effect to the low frequency, and structural strength is big simultaneously, and it is conv
