Název v původním jazyce

Aerodynamic Sound by Low Mach Numbers

Popis výsledku v původním jazyce

Air conditioning equipment ensures thermal comfort in important public buildings such as hospitals, theatres, concert halls, TV and broadcasting studios. In all these cases the indoor spaces are very demanding with respect to holding the level of noise within the required limits. Air conditioning pipe manifolds in the above buildings are terminated by inlets and outlets, which serve for the uniform supply of air. Outlets together with control elements (predominantly butterfly dampers) are in addition tothe above sources of aerodynamic noise. Usually there is not enough space to reduce the noise by means of sound dampers. The aim of the present paper, which is the result of an implemented research project, is to consider possibilities of the reductionof aerodynamic noise already in the control elements themselves.
