液压系统用于船用车辆的转向、车辆控制和公用事业服务。产生和传输噪声的系统部件是值得关注的。本SAE信息报告（a）阐述了可能适用于船舶和潜水器液压系统的噪声要求，以及（b）确定了可用于降低系统噪声的噪声源和技术。动力源（如电动机）和终端设备（如转向连杆）的噪音不在本文件范围内。

Hydraulic systems are used on marine vehicles for steering, vehicle control, and utility services. System components that generate and transmit noise are of concern. This SAE Information Report (a) addresses noise requirements which may apply to the hydraulic systems of ships and submersibles, and (b) identifies noise sources and techniques which may be used to reduce system noise. Noise of power sources (e.g., electric motors) and end items (e.g., steering linkages) is beyond the scope of this document.
