| Research Abstract |
We manufactured a high speed towing streaner cable which is installed by hydrophones nade from Piezo-Rubber. The Piezo-Rubber type hydrophones have vollowing characteristics.1) Smoll diameter and long length hydrophone 2)Casing the Piezo-Rubber with rigid brass case 3) Polyurethane mounting rail allows mechanical isolation for cylindrical plastic case 4) Maximum depth of water 500m 5) Cancelling the flow noise around hydrophme if is proved that the manufactured streamer cable has a same high performance as a intended one,
