Abstract
A sound attenuation assembly for In a forced-draft, liquid-to-air cooling apparatus, a sound attenuation assembly having at least two rows of elongate, generally cylindrical members arranged across the air inlet of the assembly to provide a blockage to the line of sight to the air flow through the sound attenuation assembly, to provide a multiple barrier effect of frontal impact on a sound front travelling through the assembly, and to provide the elongate members of sound absorbing material, which members provide improved sound attenuation associated with the force-draft apparatus while reducing back pressure losses in the air flow.
