Noise emitted by the exhausts of large internal combustion engines can cause significant environmental pollution. Hushpak wanted to improve the acoustic design of their exhaust mufflers to enable clients to reduce noise levels and meet EPA standards.
The UTS Tech Lab team developed computational software, using state-of-the-art modelling techniques, to optimise the design of Hushpak’s mufflers. A new, quieter design was tested on a mining truck and found to significantly outperform previous designs. Hushpak now use this software to create all their mufflers and are working with the Tech Lab team to expand their business into other large engine applications.
