The invention relates to an acoustic module (1) for an acoustic antenna for receiving waves under water, taking the form of a neoprene-based rubber panel (100) incorporating a plurality of tubular longitudinal ducts (2) extending along the length (L) of the rubber panel (100) and being spaced over the width (l) of the rubber panel (100), said longitudinal ducts (2) containing hydrophone columns spaced along the length (L), said rubber panel (100) furthermore incorporating at least one transverse duct (3) extending over the width (l) of said rubber panel (100), said longitudinal ducts (2) and transverse duct(s)(3) being filled with a fluid and said acoustic panel (1) being fitted with means (6) for sealing said ducts (2, 3) closed, the hardness of the rubber and the thickness of the panel (100) being chosen so that the acoustic module (1) has a first degree of freedom in flexion about an axis extending in the length (L) direction and a second degree of freedom in flexion about an axis extending over the width (l).
