The Problem

There is a sizable and growing concern about the impact of underwater noise on marine wildlife in many communities. It is known that fish and other animals can be harmed by very intense underwater sound, but at lower levels there also may be significant effects on an animal’s ability to communicate, hunt, migrate, and mate. Our system is more effective and more reliable at abating underwater noise, helping to guarantee that there will be minimal impact on the environment from industrial activities.

The Solution

AdBm Technologies has developed a patented underwater noise mitigation system which is simpler, easier to use, more effective, and has lower manufacturing costs than current technologies.  Our system uses large arrays of Helmholtz resonators, tuned to specific frequencies, to capture and mitigate noise from various noise sources.

Product & Services

The system is designed to be very flexible in its installation methodology. The Helmholtz resonator blocks are leased on a per-project basis. The system can be installed in a variety of ways: around the noise source or used to shield a sensitive marine area. Technical support and acoustic data collection and analysis are also offered. Our unique skill in producing noise abatement systems is essential, given that poorly-designed systems often show little performance and have been even been known to increase noise levels at low frequencies. In addition, our continued research in the field enables us to continually improve our methods.

Save Time

Works quicker than other systems, increase your bottom line and never hassle with air hoses, generators and dive teams again.


Use Passive Power

S4 is a passive system which removes the necessity of compressors while delivering better results at less cost.

Reduce Noise

Make partners, regulators and the environment happy by attenuating up to 50 dB.



Reduce costs and improve performance by having a system tailored to your attenuation needs.
