10.5dB Reduction on Train Compressor for Australian Rail Firm

Date: June 2012
Location: Australia


Our customer was tasked with supplying the trains for a major rail project in Australia. The trains were
required to comply with the strict Australian environmental noise regulations. The noise levels from
the air supply units fitted to each train carriage were too high for the train to meet these noise legislation targets.

The challenge for Ventac was to reduce the noise levels from these ASU units so the train could meet the regulation targets. Our solution had to be designed so that it could be fitted to the ASU units before they were installed on to the carriages of the train.
