Following noise nuisance complaints from residents opposite the factory, an industrial food manufacturer asked Advanced Noise Solutions Ltd for help with noise suppression from some roof extract fans. We carried out various noise tests and gave the company four noise suppression options from which to select in order to reduce the noise from the fans. However, we also pointed out that solely treating the fans would not be sufficient because there were also high levels of noise transmission from various types of industrial production machine inside the factory. Noise levels were between 90 dBA and 97 dBA in many production areas inside the factory.
We recommended that a new industrial steel door be fitted to the outside wall of the factory to provide noise suppression for the industrial production machines. We also recommended that various types of industrial production machine be treated at source if a further noise reduction was needed afterwards. This would have the major benefit that it would provide suppression of worker noise exposures as well as noise nuisance.
Following noise suppression of the fans and installation of the new factory door, complaints ceased. However, the company plans to carry out further noise suppression work in future by treating various types of industrial production machine in the factory at source, as we recommended.
