Abstract

Industrial fans, used in a wide variety of applications, are a major source of noise. In most cases, the noise has a low-frequency tonal component that defies conventional noise reduction techniques. The Université de Sherbrooke’s acoustic research group (GAUS) has developed an innovative technology, named SimpleSilence, that has the potential to reduce these tonal components. The technology can be applied to existing systems without the need for expensive upgrades or replacement of fans already in service.
The purpose of this study is to demonstrate SimpleSilence’s potential to reduce the noise made by industrial fans.
