Abstract (en)
[origin: EP0291892A2] A compliant baffle for use in a marine environment wherein a pair of plate-like elements (30, 32) are separated in a spaced predetermined manner typically employing T-blocks, rods, or edges (34, 36) of the plate-like elements bent one towards the next, surrounded by an elastomeric encapsulant (48) and configured into ranks of box-like structures (12) forming a sonic reflector (10) or baffle. The baffle finds utility in reflecting noise in especially at great depths in marine environments.
