Abstract : An acoustic envelope is provided which may include a tubular sheath which is mounted about a conducting element. The tubular sheath has inner and outer tubular portions which are integral with respect to one another. The acoustic envelope further includes a plurality of non-elastic strands which extend longitudinally along the sheath between the inner and outer tubular portions and which ar ebonded thereto. The tubular sheath is constructed of a material which optimally minimizes vibration induced noise and flow induced noise when the line array is towed through the water. (Author)
