Sound attenuation refers to reducing noise levels. Minetek Sound enables the world’s quietest mining equipment and machinery, reducing noise levels by up to 50%. Our solutions are designed to minimise the weight of components without compromising machine integrity, airflow, and maintenance access.

Reducing noise levels in mining operations helps to minimise potentially harmful safety impacts on operators, ensuring a safer working environment. It also helps mining operations meet regulatory and community noise expectations, enhancing compliance and community relations.

Minetek’s sound attenuation solutions can be used in various applications, including both mobile and fixed assets such as haul trucks, excavators, dozers, blast hole drill rigs, graders, loaders, water trucks, generators and acoustic enclosures.

Minetek has developed proven sound packages for over 90 different OEM models, with more than 1,500 mining machines fitted with Minetek sound packages. Some of the OEMs include: Liebherr, Komatsu, Caterpillar, Hitachi, Terex, Sandvik, LeTourneau, Epiroc and NHL.

Minetek provides a comprehensive range of noise testing services, including:

• Compliance testing as per the ISO 6393/6395 Standard
• Sound intensity testing
• Mobile fleet screening
• Operator noise exposure testing

Minetek works closely with clients to develop practical mitigation solutions that are workable for the mining company. Our deep-domain experience in sound auditing and testing, combined with a consultative approach, provides confidence that operations and machinery will comply with regulatory and community obligations.

Yes, Minetek stocks a wide range of replacement parts and accessories to ensure that operations can quickly respond to failures and breakdowns, reducing potential costly downtime. Access to a dedicated inventory of replacement parts ensures the continuity of operations and productivity.

Minetek manufactures industrial exhausts for mining machinery and leading OEMs. These exhausts are designed with sound reduction properties that vary with the machine’s acoustic frequency. Minetek exhausts can target specific frequencies, including balance and noise-canceling configurations, and incorporate substantial heat reduction capability.

Ensuring OEM airflow is maintained is a primary engineering principle at Minetek. Our sound suppression components are designed to reduce overall machine noise output without compromising the airflow essential for the machinery’s operation and performance.

Minetek’s approach to sound attenuation is unique due to our innovative engineered solutions, deep-domain experience, and commitment to a consultative approach. We provide tailored solutions that meet regulatory and community noise expectations while ensuring the integrity and performance of mining machinery.
