"The main topic of this paper is to present the results of experimental measurements and analyses of the causes of generation of acoustic energy in small holes and/or slots with a variable width. The measured sound power levels for individual types of slots are related with non-dimensional similarity criteria. The levels of sound power are further related with pressure conditions in the slot. The results are formulated as recommendations for the design of control dampers used in HVAC systems."@en . "Z(MSM6840770011)" . . . "Noise of Small Holes and Slots"@en . "202335" .
