Hushpak Engineering specialises in noise control solutions for the mining, manufacturing and construction industries. We design and manufacture bespoke noise attenuation products, with particular experience in source attenuation of mobile machinery (including dozers, haul trucks, graders and excavators) as well as barriers and enclosures for noisy industrial operations and road noise.

As leaders in noise control solutions, we are committed to providing effective noise control solutions that attenuate sound at the source without compromising the performance, operation or maintainability of the equipment.  In fact we have attenuated haul trucks and graders so they pass the noise test whilst improving machine accessibility,  improving safety of maintenance tasks and without increasing engine back pressure.  We have achieved up to 6 dB(A) noise reduction using our exhaust and muffler systems and cooling fans.

To effectively reduce unwanted noise, we first need to understand the noise profile of the machine or equipment.  We follow International Standards for dynamic and stationary test conditions when evaluating noise impacts of earth-moving machinery, or rely on acoustic results from NATA certified laboratories.  We also conduct noise modelling, assessment of machinery sound power levels, noise source measurement, sound intensity and discrete frequency analysis. 

Our strong R&D focus ensures we keep abreast of new sound attenuation products and acoustic materials. Having noise tested hundreds of mobile machines, Hushpak has proven knowledge of acoustics and predominant noise sources. Our specifically engineered solutions are developed using sophisticated analytics and design tools to achieve exceptional results with less capital outlay. Our strict quality control procedures ensure high quality products are designed and manufactured in our Newcastle facility.

With 20 years’ experience…. we are the quiet achievers.
