Underwater Noise Pollution Mitigation
Underwater sound attenuation
The impact of underwater noise on aquatic species is both significant and increasingly recognised, with much of the key research emerging in the past decade. Sources include construction activities such as piling and demolition, commercial shipping, and UXO detonations.
For projects in rivers, estuaries, ports, and coastal or offshore environments, managing underwater noise and vibration control is now a critical responsibility. Without early engagement, noise-related risks can threaten project timelines, regulatory compliance, and environmental stewardship.
As the UK supplier of Bubble Tubing® for commercial sound attenuation, we deliver proven, experience-led solutions for underwater noise control. Our award-winning work has made effective sound mitigation more accessible, reducing costs without compromising performance.
Well-planned, site-specific systems can create operational advantages as well as meet environmental obligations. For example, tailored sound attenuation designs have enabled extended working windows across tidal phases, delivering measurable savings on preliminaries and overall project costs.
In high-stakes situations such as UXO detonations, where sound control is essential but often expensive, our Bubble Tubing® systems make this critical technology more economically viable for a wider range of projects.

Solutions to reduce noise and vibration underwater
Revolutionising
Protection during impact piling and construction
We’ve won international awards for pile driving noise mitigation through our Bubble Tubing systems. They create effective sound curtains that attenuate underwater noise during impact piling and help reduce disturbance to sensitive aquatic life, meeting environmental licence conditions.
Protecting aquatic life and marine mammals
Our sound attenuation solutions that balance performance, simplicity and sustainability help reduce the impact of noise on protected species such as salmon, seahorses, and marine mammals. By mitigating stress and behavioural disruption, we actively support both regulatory compliance, environmental stewardship and conservation.
Facilitating regulatory approvals and MMO licensing
Our technology has supported successful Marine Management Organisation (MMO) licence applications, reducing regulatory restrictions and expanding operational windows.
Dual-purpose technology
In addition to sound control, Bubble Tubing provides high-performance aeration. This can improve dissolved oxygen levels, benefiting water quality while fulfilling sound attenuation roles.
Cost-effective noise control
By improving the affordability of sound mitigation systems, we’ve helped bring high-quality noise control within reach of more projects, without sacrificing technical performance.
Training and deployment support
We offer targeted training to upskill teams and build environmental awareness and hands-on guidance to ensure underwater noise mitigation systems are installed and operated effectively on site, maximising both performance and regulatory confidence.
