Redefining Noise Control in Mining: Minetek Sound’s Advanced Testing

In mining operations, noise from heavy machinery isn’t just an annoyance—it’s a serious risk to worker safety, can impact surrounding communities, and can challenge regulatory compliance. With effective noise reduction solutions, however, these risks can be minimised, creating safer, more productive work environments.

Minetek Sound approaches this challenge with a unique blend of acoustic expertise and mechanical innovation. For over 25 years, we’ve redefined what quiet mining machines can be, developing noise reduction solutions that make Minetek the creator of the world’s quietest mining machines, reducing sound levels by up to 50%.

Our process starts by identifying major noise sources within mining machinery. Through advanced sound testing and analysis, Minetek engineers measure exposure levels and pinpoint areas for noise reduction. This proactive approach not only safeguards workers’ hearing but also improves operational conditions, enabling a safer, more productive workplace.

What is sound testing?

Sound testing measures sound pressure levels (SPL) to evaluate the noise emitted by specific sources, providing essential insights into the performance of noise attenuation systems by analysing key aspects of noise emission and its impact.

At Minetek, our sound testing solutions go beyond simple measurements—they lay the groundwork for developing comprehensive sound attenuation and noise mitigation programs. Tailored to each operation’s unique needs, these programs address specific noise challenges, delivering effective, targeted solutions for optimal noise control.

What are the benefits of sound testing?

Sound testing is central to Minetek Sound’s noise reduction strategy, offering key advantages that support effective noise management in mining operations.

Understanding Noise Sources: Through sound testing, we conduct a detailed analysis of noise emissions from specific machinery or equipment. By measuring sound pressure levels (SPL) at multiple points around the source, engineers can assess noise intensity and distribution, pinpointing which components or operational factors contribute most to overall noise levels.

Strategic Placement: Sound testing also identifies the optimal locations for installing noise reduction equipment. By measuring noise levels throughout the environment, engineers can focus mitigation efforts on the most problematic areas, ensuring that noise reduction solutions are targeted where they’ll have the most significant impact, rather than applying a broad, one-size-fits-all approach.

This targeted methodology ensures maximum effectiveness in reducing noise, creating safer and quieter mining operations.

Assessing Effectiveness: Sound testing enables us to evaluate the real-world performance of noise attenuation systems. By comparing noise levels before and after implementing control measures, Minetek engineers can assess the effectiveness of each solution and pinpoint areas for further enhancement.

Optimising Design: For new equipment or installations, sound testing is vital to understanding how design modifications impact noise performance. This continuous assessment ensures that designs are refined for optimal noise reduction while preserving equipment efficiency and functionality.

Community Relations: Sound testing also addresses community concerns around noise pollution. By demonstrating that noise levels are controlled and reduced to acceptable levels, Minetek supports mining operations in maintaining positive relationships with local communities.

Compliance with Global Standards: Minetek Sound’s testing solutions adhere to ISO 6393 and 6395 standards, internationally recognised benchmarks for noise testing in machinery and equipment. By integrating these standards, we ensure that our testing methods align with global best practices, delivering reliable and consistent results.

Our commitment to these standards underscores our dedication to quality and credibility, demonstrating that our noise control solutions not only meet but often exceed international requirements for noise management.
