This example shows a well known type of biscuit being made at a major food company in the UK. In the background, the vibrating feeders are visible. These transport the biscuits to operators who load them into boxes. The vibrating feeders were the main noise source for these workers. Our engineering solution provided a substantial noise reduction without covering or enclosing the vibrating feeders, so retaining full visibility of, and access to, the biscuits.
Engineering noise solutions also cost considerably less than fitting acoustic enclosures around vibrating feeders.
