Abstract

Vorgeschlagen wird eine Vorrichtung zur Senkung des Schallpegels von Unterwasserschallquellen, mit
□ einem Schallpegel reduzierenden Umhüllungselement (2), Öffnungen (4, 5) zur Abgabe eines gasförmigen Stoffes aufweisend,
□ einer zentralen Ausrichtungskomponente (1) für das Umhüllungselement (2),
□ Mitteln (3) zur beabstandeten Ausrichtung des Umhüllungselements (2) entlang der zentralen Ausrichtungskomponente (1),

wobei die vorgeschlagene Vorrichtung dadurch gekennzeichnet wird, dass
■ Mittel (3) zur beabstandeten Ausrichtung des Umhüllungselements (2) kettenartig miteinander verbundene Gliederelemente umfassen, geeignet zur Ausbildung einer ziehharmonisch streckbaren Führung für das Schallpegel reduzierenden Umhüllungselement (2).

Proposed is a device for lowering the sound level of underwater sound sources, with
□ a sound-level reducing cladding element (2), having openings (4, 5) for discharging a gaseous substance,
□ a central alignment component (1) for the cladding element (2),
□ means (3) for the spaced alignment of the sheath element (2) along the central alignment component (1),

the proposed device being characterized in that
■ means (3) for the spaced alignment of the sheath element (2) chain-like interconnected link elements comprise, suitable for forming a zieherharmonisch stretchable guide for the sound level reducing sheath element (2).
