Abstract
A device for and methods of reducing sound vibrations in a liquid resulting from a sound source arranged below the liquid level of a body of water are disclosed. The device includes an elongate tube which can be arranged over the sound source, the tube comprising an outer wall and inner wall with an intermediate space between the inner and outer wall.

A device for the passive reduction of the sound vibrations in a liquid resulting from a sound source arranged below the liquid level of a body of water, the device comprising an elongate tube which can be arranged over the sound source and, in use, extends to a level above the liquid level, the tube comprising an outer wall, an inner wall and an uninterrupted and sealed intermediate space in between the outer wall and the inner wall and along the entire length of the tube, extending in the longitudinal direction of the tube, with the contents of the intermediate space between the inner and outer wall being formed completely by gaseous matter for reducing vibration transmission via the intermediate space to the body of water.
A device for the passive reduction of the sound vibrations in a liquid resulting from a sound source arranged below the liquid level of a body of water, the device comprising
- an elongate tube which can be arranged over the sound source;
- and
- pump means able to at least partially pumping out a central interior space delimited by the tube and extending above the liquid level in order to reduce the transmission of noise from the sound source to the inside of the tube.
A method for the passive reduction of the sound vibrations in a liquid resulting from a sound source arranged under the liquid level of a body of water, the method comprising:
- positioning a tube in the body of water around the sound source, the tube with an uninterrupted and sealed intermediate space in between an outer wall and an inner wall and extending above the liquid level;
- and
- anchoring the tube at the bottom end and/or the top end.
