Summary

The article deals with sound transmission of circular cross-section ducts manufactured of relatively thin sheet metal. The noise generated from duct systems surfaces, where the high level of acoustic pressure is caused first of all by the high acoustic output of fans, or frequently by noise related to gases combustion at combustion equipment, is very frequently left out on the ground of the unfamiliarity with the mechanism of its radiation. The article deals with cases when the duct of rectangular cross-section was manufactured of steel sheet.
