水下声学 水下环境噪声的测量

[中文适用范围]： 本文件提供了测量和报告水中环境声音的要求和建议，以声压和可从声压导出的选定量为特征。“环境声音”指除自噪声源外的任何来源的声音。范围包括设备性能、校准和部署、数字数据采集和数据处理。数据处理是将原始数据转换为人和计算机解释所需形式和上下文的过程。范围包括持续一天或更长时间的记录的数据分析和报告。考虑了五个数据处理阶段：原始数字采集数据、声压时间序列、声压级时间序列、声压谱及其统计。范围不包括粒子运动的测量。 [外文原描述]： This document provides requirements and recommendations for measuring and reporting ambient sound in water, as characterized by sound pressure and selected quantities that can be derived from sound pressure. “Ambient sound” implies sound from any source except sources of self-noise. The scope includes equipment performance, calibration and deployment, digital data acquisition and data processing. Data processing is the process of converting raw data into a form and context necessary to be interpreted by people and computers. The scope includes data analysis and reporting of recordings of duration one day or longer. Five data processing stages are considered: raw digital acquisition data 3) , sound pressure time series, sound pressure level time series, sound pressure spectra and their statistics. The scope excludes measurement of particle motion. 3) The word data is generally used as a collective noun in this document; the plural form is reserved for cases where the constructive relationship to individual observations or measurements is to be emphasized.
