Abstract [en]

Downsizing in cars lead to higher noise emissions through the addition of turbo-/superchargers. These noise emissions must be counteracted and cancelled in order to contribute to the overall quality feel of a car. This project follows a product development method in order to research if a new type of silencers are applicable in air induction systems in order to dampen noise emissions. The project also cover how to manufacture the new type of silencers, traditionally used as acoustic insulation in offices.

The project covered everything from literature review on silencers, noise regulations, downsizing and traditional plastic manufacturing methods. After the analysis of the results, it stood clear that the new silencers are more effective than conventional solutions. A manufacturing process was also determined, which needs further research in order to derive what the manufacturing cost would be. The project resulted in strong indicators that the new silencers are promising but also opened up to new research questions.
