Use of Dissipative Silencers for Fan Noise Control
-
Descrição
-
Axial and centrifugal fans are very used in industries in general. These equipments have great applicability in the product development as well as ambient comfort. Among the operational problems in these equipments, the noise frequently arises as principal causes. The fundamental approach is the utilization of absorptive, parallel, or circular baffle-type silencer. The features of this type of silencer are good high-frequency attenuation and minimal aerodynamic pressure loss. In this context, this work presents a review of the common noise sources in fans and the procedures for noise attenuation. Finally, an application case is presented to illustrate the use of dissipative silencer.
