Frequently asked questions

Discover the answers to our most asked questions.

What is sound attenuation, and how does Minetek Sound achieve it?

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.

What are the benefits of reducing noise levels in mining operations?

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.

In what applications can Minetek’s sound attenuation solutions be used?

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.

What OEM models have Minetek sound packages been developed for?

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.

What types of noise testing and auditing does Minetek provide?

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
How does Minetek ensure compliance with safety, regulatory, and community expectations?

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.

Does Minetek offer replacement parts for its sound attenuation solutions?

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.

 

What are Minetek’s industrial exhausts, and how do they work?

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.

How does Minetek ensure OEM airflow is maintained with sound suppression components?

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.

What makes Minetek’s approach to sound attenuation unique?

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.
