近日，三星重工（SHI）宣布成功开发出一项新技术，能够通过声纳探测海洋声波信号，精确分析船舶水下辐射噪声。声纳信号分析法是接收噪声源发出的声音并测定噪声的强度、方向和距离的一种技术。利用此技术，三星重工精确分析了一艘17.4万立方米级液化天然气（LNG）运输船的噪声源。他们表示，会进一步提升相关的技术研发能力，例如，分析在建船舶水下辐射噪声的产生原因及影响，根据船舶的航行速度和吃水深度等预测其噪声级。目前，国际海事组织（IMO）正在考虑制定有关水下噪声的法规，船舶降噪技术的重要性越发凸显。

Samsung Heavy Industries announced that it has secured a technology to precisely analyze the underwater radiation noise of ships by analyzing the sound wave signals detected through sonar. The sonar signal analysis technique is a technology that measures the intensity, direction, distance, etc. of noise by receiving the sound emitted by the noise source. Reportedly succeeded in precisely analyzing the cause of the noise of a 174,000㎥ class super-large LNG carrier. Using this technology, Samsung Heavy Industries has been able to further strengthen its expertise in developing related technologies, such as segmentation and impact analysis of causes of underwater radiated noise for ships built using this technology, and forecasting noise by operation speed/draft. Accordingly, the International Maritime Organization (IMO)  is actively discussing regulations on radiated noise in the water, and the importance of noise reduction technology development is gradually increasing.
