advanced air diffusion INTRODUCTION 1. Overview The last stage of the air working-out process so called "Treated" is the air-diffusion into rooms. The purpose of the air-diffusion into rooms is that to homogenize to the established values the temperature parameters, relative humidity, speed and air-purity, so that to obtain the best comfort conditions for the people that uses those rooms. Through the suitable so called ending units is taken the treated air into the rooms. The ending units could be of give-out, of intake, ejection, of expulsion or of transit according to the specific function...

The sound level used in this planis referred only to the ending units and do not consider the ambient reduction or the disposition of other near units. Is up to the planner tovalue the throw-direction factor, the distance from occupied area, the absorption coefficient and the ambient constant, so to valuate the correspondence or not to the acoustic requirements that the treated room has to satisfy.
