The lightweight underwater acoustic baffle with enhanced performance characteristics particularly at low frequencies is provided by a stiffened resistive screen means affixed in front of a compliant material for allowing the baffle to reflect on the compliant side and on the screen side, a rigid irregular shaped material means with a primary open surface area affixed to the screen as a means for attaining maximum stiffness with a minimum weight, a compliant means affixed behind the screen means, a water fluid sealing and container means within the baffle means for suffusing the stiffening core area and its attached screen for generating miniscule acoustic resistance in the screen and producing a greater impedance mismatch thus enhancing the insertion loss and baffle performance, and, an attachment affixed to the container means for attachment to a vessel.
