Targeted Frequency Acoustic Project

Overview

Faced with stringent noise compliance requirements for a Rolls Royce Bergen Engine, our client sought a robust acoustic solution that could effectively target the problematic 40Hz frequency range. The existing equipment, installed by a third party, failed to meet performance expectations — prompting a need for complete system redesign and execution.

Challenge

• Eliminate excessive low-frequency noise at 40Hz.
• Replace underperforming existing acoustic solutions.
• Maintain operational temperature control while integrating into an existing power infrastructure.
• Ensure minimal disruption to ongoing operations during installation.

Solution

Through close collaboration between our sales and technical teams, we developed a custom-engineered acoustic exhaust system tailored to the client’s specifications. Key features included:

• Custom Exhaust Silencers: Engineered specifically to target and reduce the 40Hz frequency output.
• Mild Steel Interconnecting Pipework: Designed for durability and acoustic continuity, finished with stucco aluminium cladding to control heat and mitigate noise transmission.
• Acoustic Enclosure: A fully bespoke housing enveloped the entire exhaust system, enhancing sound attenuation and ensuring compliance with environmental noise regulations.

To ensure optimal performance, we also:

• Dismantled and removed the existing ineffective equipment.
• Deployed our IMS Service Engineers for precise installation and commissioning.
• Executed contract lifts with qualified operators and full banksman support to manage equipment handling safely and efficiently.

Results

• Achieved significant reduction in noise levels at the target 40Hz frequency.
• Delivered a reliable, high-performance acoustic solution meeting client and regulatory standards.
• Seamless installation with no unplanned downtime, thanks to integrated project management and field expertise.

Conclusion

This project showcases our ability to deliver complex, frequency-specific acoustic engineering solutions tailored to high-performance engines. By integrating design, fabrication, removal, and installation services under one roof, we ensured quality, efficiency, and compliance from start to finish.
