A plurality of streamer-cable bulkheads mounted within a streamer cable in cascade for radially scattering tube-wave noise from a streamer-cable. Each bulkhead consists of an annular body with conical surfaces converging at a desired angle, extending outwards from both ends of the annular body. An axial hole and a plurality of off-axial holes extending through the bulkhead for receiving therethrough, electrical conductors and stress members respectively. Noise traveling within the tube in a waveguide mode, impinges upon the conical surfaces of the cascaded bulkheads, and is reflected out of the streamer-cable jacket.
