Big Bubble Curtain Hose – Noise Mitigation Systems for Offshore Wind Construction
Big bubble curtain hose is used for noise mitigation caused by underwater construction, often anchoring of foundations for wind turbines. Sound intensity can reach 180 dB, equivalent to a rocket launch, causing distress and harm to noise sensitive porpoises and marine life.
What is a big bubble curtain hose?
Big Bubble Curtains are made from perforated hose laid in a ring around the noise source. The hose creates a curtain of air bubbles generated by compressed air, resulting in a change in the density of the water, breaking up the sound waves. Construction noise is significantly reduced.
