Gunderboom® SAS™ Sound Attenuation System (continued)
Protection against high and low frequencies
Submarine construction activities such as underwater demolition and pile driving generally produce sounds over a broad and varying frequency range. By integrating several sound attenuation techniques, Gunderboom's SAS™ cushions against sound waves of all frequencies, including far-reaching, low-frequency sounds that are the most damaging.
How the Gunderboom® SAS™ works
Comprised of water-permeable polypropylene/polyester fabric, the patented, double-layer SAS™ curtain is either suspended by flotation billets and anchored in place, or installed on a rigid frame surrounding the area of activity. As compressed air is released at the bottom of the curtain, the space between the two fabric layers inflates, creating a sound-absorbing bubble wall.
