ABSTRACT:
The disclosed silencer has noise-absorbing partitions disposed in a gas duct in parallel with but with a spacing from outer walls of the duct, so as to define gas passage means and noise-absorbing space means in the duct. The noise-absorbing space means is closed by noise-shielding plates at inlet and outlet ends of the duct. A plurality of gas chambers aligned along the line of gas flow through the duct are formed in said noise-absorbing space means by disposing noise-shielding sectional walls therein.
