本文件规定了通过转换计算等效单极源电平的方法 根据ISO 17208-1在深水中获得的辐射噪声级值。并给出了程序 用于根据特定水听器几何形状在深水中进行的测量进行直接计算。这个 根据本文件中的程序计算出的源电平是一个等效单极子源的电平 指定的标称震源深度，且仅适用于侧面。标称震源深度旨在 用等效单极横向源电平值报告。交叉引用:IEC 61260-1ISO 18405ISO 17208-1:2016ISO/IEC指南98-3:2008购买时可用的所有当前修订版均包含在本文件的购买中。

This document specifies methods for calculating an equivalent monopole source level by converting radiated noise level values obtained in deep water according to ISO 17208-1. Procedures are also given for direct calculation from measurements made in deep water with specific hydrophone geometry. The source level calculated by the procedure in this document is that of an equivalent monopole source at a specified nominal source depth, and for broadside aspect only. The nominal source depth is intended to be reported with the equivalent monopole broadside source level value.Cross References:IEC 61260-1ISO 18405ISO 17208-1:2016ISO/IEC Guide 98-3:2008All current amendments available at time of purchase are included with the purchase of this document.
