海洋能源.波浪 潮汐和其他水流转换器.第40部分:海洋能源转换器的声学特性

[中文适用范围]： IEC TS 62600 标准的第 40 部分提供了统一的方法论，用于一致地表征产生电力的海洋能转换器的运行声音，包括波浪、电流（潮汐、海洋和河流）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表征，也不建立用于确定环境影响的阈值。表征是指在特定距离、深度和方位上接收到的海洋能转换器声音。信息性附件 B 提供了用于估算声源级所需额外测量的指导。本文件的范围包括表征海洋能转换器附近声音的方法与仪器，以及为监管机构、行业和研究者展示该信息的方式。给出了仪器校准、特定类型海洋能转换器周围的部署方法、分析程序和报告要求的指导。本文件适用于单个转换器和阵列的声音表征。本文件主要描述单个转换器的测量程序，阵列的扩展在信息性附件 A 中讨论。 [外文原描述]： 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.
