IEC TS 62600-40:2019提供了统一的方法来一致地表征发电的海洋能源转换器运行产生的声音，包括波浪、海流和海洋热能转换。本文件不包括与这些转换器的安装、维护或退役相关的声音特征，也没有建立确定环境影响的阈值。表征是指海洋能量转换器在特定范围、深度和方向处接收到的声级。 本文件的范围包括表征海洋能源转换器附近声音的方法和仪器，以及供监管机构、行业和研究人员使用的这些信息的呈现。为仪器校准、特定类型海洋能源转换器的部署方法、分析程序和报告要求提供了指导。 本文件适用于来自单个转换器和阵列的声音的表征。本文件主要描述单个转换器的测量程序，并扩展到资料性附件中讨论的阵列。

IEC TS 62600-40:2019 provides uniform methodologies to consistently characterize the sound produced by the operation of marine energy converters that generate electricity, including wave, current, and ocean thermal energy conversion. This document does not include the characterization of sound associated with installation, maintenance, or decommissioning of these converters, nor does it establish thresholds for determining environmental impacts. Characterization refers to received levels of sound at particular ranges, depths, and orientations to a marine energy converter.
The scope of this document encompasses methods and instrumentation to characterize sound near marine energy converters, as well as the presentation of this information for use by regulatory agencies, industry, and researchers. Guidance is given for instrumentation calibration, deployment methods around specific types of marine energy converters, analysis procedures, and reporting requirements.
This document is applicable to characterization of sound from individual converters and arrays. This document primarily describes measurement procedures for individual converters, with extension to arrays discussed in informative Annex.
