ISO/PAS 17208-1:2012描述了在规定操作条件下测量船舶水下声压级所用的一般测量系统、程序和方法。它提出了一种报告三分之一倍频程声压级的方法。由此产生的量是标准化为1 m距离的声压级。水下声压级测量在几何远场中进行，然后调整为1 m标准化距离，以便与适当的水下噪声标准进行比较。 ISO/PAS 17208-1:2012没有规定或提供水下噪声标准指南，也没有说明噪声对海洋生物的潜在影响。 它适用于任何和所有有人或无人驾驶的水上航行船舶。其方法对最小或最大血管大小没有固有限制。它不适用于水下船舶或飞机，仅限于以不超过50节（25,70米/秒）的速度通过的船舶。测量方法减轻了劳埃德镜面图像相干效应造成的可变性，但不排除传播效应（如底部反射、折射和吸收）的可能影响。没有给出这些影响的具体计算调整。ISO/PAS 17208的应用不需要特定的海洋位置- 1:2012，但提供了海洋试验场地的要求。 ISO/PAS 17208-1:2012的应用包括显示符合合同要求、启用定期签名评估以及研发。预期用户包括政府机构、研究船运营商和在声学敏感水域运营的商业船所有人。

ISO/PAS 17208-1:2012 describes the general measurement systems, procedures and methodologies to be used to measure underwater sound pressure levels from ships at a prescribed operating condition. It presents a methodology for the reporting of one-third-octave band sound pressure levels. The resulting quantities are the sound pressure levels normalized to a distance of 1 m. The underwater sound pressure level measurements are performed in the geometric far field and then adjusted to the 1 m normalized distance for use in comparison with appropriate underwater noise criteria. ISO/PAS 17208-1:2012 does not specify or provide guidance on underwater noise criteria or address the potential effects of noise on marine organisms. It is applicable to any and all underway surface vessels, either manned or unmanned. Its methods have no inherent limitation on minimum or maximum vessel size. It is not applicable to submerged vessels or to aircraft, and is limited to vessels transiting at speeds no greater than 50 knots (25,70 m/s). The measurement methods mitigate the variability caused by Lloyd's mirror surface image coherence effects, but do not exclude a possible influence of propagation effects such as bottom reflections, refraction and absorption. No specific computational adjustments for these effects are given. A specific ocean location is not required for the application of ISO/PAS 17208-1:2012, but requirements for an ocean test site are provided. Among the applications of ISO/PAS 17208-1:2012 are the showing of compliance with contract requirements, the enabling of periodic signature assessments and in research and development. Intended users include government agencies, research vessel operators and commercial vessel owners operating in acoustically sensitive waters.
