摘要：

Towed arrays of hydrophones are used as large aperture sonars by the seismic industry and by many navies. Flow noise originating in the turbulent boundary layer often limits the performance of these sonars. The flow noise can be reduced by filtering certain wave numbers using an elastic tube, groups of hydrophones, or extended hydrophones. The amount of noise reduction is investigated in cylindrical geometry for different extended hydrophones, and for solid- and fluid-filled tubes. (C) 1996 Acoustical Society of America.
