水下声学冲击打桩辐射水下声的测量水下屏障控制措施插入损耗的现场测定

[中文适用范围]： 本文件规定了两种用于水下噪声消减措施（噪声消减系统）插入损失的原位测定程序。使用压载驱动发出的冲激声作为研究噪声消减系统的声源。 本文件不适用于人工声源和实验室条件下的调查。 除正确安装相应的噪声消减系统外，所获得的声音衰减还取决于安装条件（例如锤击类型、驱动力、桩尺寸）以及环境条件（例如水深、海底分类和地形、水流和风力条件）以及通过海底的旁瓣传输。 [外文原描述]： This document specifies two procedures for the in situ determination of the insertion loss of underwater noise abatement measures (noise abatement systems). The impulsive sound of pile driving is used as the sound source for the investigation of noise abatement systems. This document does not apply to artificial sound sources and investigations under laboratory conditions. Apart from the correct application of the respective noise abatement system, the achieved sound attenuation also depends on the installation conditions (e.g. type of hammer, driving energy, pile dimensioning) as well as on the environmental conditions (e.g. water depth, seafloor classification and bathymetry, current and wind conditions) and the flanking transmission via the seafloor.
