Simple noise control solutions for building systems - Three case studies
Abstract
Conventional methods of controlling noise generated by building HVAC (Heating, Ventilation and Air-Conditioning) systems depend on using silencers, lagging, barriers and or room treatments. Cost benefits of these approaches as well as physical feasibility of applying these methods, for retrofit situations in particular, prohibit any meaningful applications. Three severe noise situations demanded serious rethinking of applying conventional methods and demanded innovative approaches. The investigation of the noise concerns as well as the methods applied to attenuate and/or eliminate the noise problems are presented in this paper.
