Characteristics of Underwater Noise Levels of Large Vessels in the Yeosu Bay

This study aimed to understand the characteristics and noise levels in large vessel entering, leaving, and anchoring in a port. Air and underwater noise were measured at the stem, middle deck, and stern of a vessel (about 30,000 tons and 60,000 tons, respectively) during anchoring. In addition, variations in noise were observed in the moving range of vessels while entering and leaving in a port. The air and underwater noise levels were found to be higher in the stern than in the stem and middle deck during anchoring. The noise was changed by tugs, engine use, and the moving range of target vessels while entering and leaving in a port.
