Specialised Equipment
Handheld Array for Acoustic Holography
Acoustic Holography is used for noise leak detection and identification of high priority emission sources for better designed acoustic attenuation controls.
Site Auditing (Environmental Noise)
Mammoth can assist with noise emission management plans by conducting a thorough audit of site operations and testing and observing equipment noise emissions at various operational zones throughout the site.
Services and Process
Relevant Experience
Mammoth is a leading solution provider to the global mining industry and a specialized manufacturer of noise attenuation engineering controls for earth-moving machinery.
We provide sound attenuation products, overhaul and refurb kits, consultancy and testing services to support sites and operators meet their compliance targets and reduce occupational exposure to high levels of industrial noise.
Mammoth is familiar with noise measurement and testing standards, and has undertaken numerous SWL measurement exercises for mobile equipment using various methodologies, both on site and in workshops
