Abstract
Defence R&D Canada – Suffield is investigating methods of reducing the acoustical signatures of a variety of small all-terrain vehicles (ATVs). Before vehicle modifications are conducted on a test ATV platform, a set of baseline measurements are required to establish the noise level of the unmodified platform. It is also important to define the noise reduction achievable with commercially available mufflers as a benchmark for the custom solutions developed under this project. As such, HGC Engineering analysed the sound levels produced by a Polaris Big Boss 6x6 ATV with its factory exhaust system, and also with several “silent” muffler systems. The study found that the most effective approach existing approach for reducing noise without reducing vehicle power is using two Polaris factory mufflers in series.
