"Environmental Engineering of Buildings, which is content of research program MSM 210000011, is divided in 5 parts, Ventilation and Air-conditioning, Heating, Air pollution, Noise Control and Eskalators. This work deals with problem of duct elements generated sound power. The There are two possible sources in a duct. One is associated with noise generated by a fan. Flow generated noise is the result of air flow turbulence which has usually been concetrated into a discrete region. The noise generated at outlet grilles is strongly velocity-dependent." . . . .
