Sound suppression problems? We're here to help

When it comes to sound suppression for your fleet, there’s a lot that can go wrong. Do any of these problems sound familiar to you:

  • Your sound suppression system isn’t compliant?
  • Difficult to access the engine bay area?
  • Can’t access the engine due to pipes being in the way?
  • Underbelly guards and engine doors fall off?
  • Trucks are heavy with a bulky attenuator and fan?
If you’ve experienced any of these issues, then we’re here to help. We offer a different approach with staged attenuation that you can implement in stages.


With fewer bulky suppression add-ons, your trucks can benefit from increased payloads, and you’ll save on your upfront sound investment also. Remember, when it comes to sound, not one size fits all.

Staged Attenuation – lower upfront cost and increased payloads

We offer staged design and a structured method to implement noise attenuation via a multi-staged methodology. Rather than the 'one size fits all' mindset, our modular approach provides a point-of-difference allowing our clients to utilise staged attenuation for haul trucks and mobile mining equipment. This often translates into weight and cost-saving benefits.

Our product range includes custom-designed sound suppression exhaust packages with noise attenuation kits for mechanical components for subsequent stages. Key features of these stages are as follows:

  • Multi-staged attenuation packages
    • Option to pay for and implement products/stages as required
    • Our modular approach enables staged attenuation and cost savings
    • Multi-staging improves weight distribution with superior sound suppression and optimal backpressure
    • Turnkey solutions custom-designed to suit your requirements
