Abstract (en)
[origin: EP0328931A2] A compliant tube baffle for use in a marine environment wherein a boxlike structure (10) is surrounded by an elastomeric cover (64) and includes a pair of elastic tapered beam plates (12,14) separated by suitable means such as by bent plate springs (18,20) which may be engageable with elastic cushioning layers (54) adhered to side shields (52). Damping may be provided by piezoelectric elements (58) or by constrained layers (66) of elastomeric material stressed during flexing movement of the beam plates (12,14).
