| 摘 要： | 采用船舷法对某海域海洋环境噪声垂直分布进行了测量.数据处理与分析结果表明,在6种接收深度下,当地的海面风生破碎波浪噪声对环境噪声有显著贡献.给出了所测海域环境噪声在0.1～20.0kHz频段的宽带声级和接收深度以及多种频率谱级与风速的对数之间的关系.1.0～4.0kHz频段的谱级与风速的对数呈良好的线性关系,且基本上不受接收深度的影响.

| Abstract: | The vertical distribution of ocean ambient noise is measured by a vertical array beside shipboard. The results of data processing and analyses show that the wind-generated noise induced by the local wave-breaking contributes much to the ambient noise in six different depths. Both the relations between the ambient noise levels in the frequency band from 0.1 to 20.0 kHz and the receiver depth,and between the ambient noise spectrum levels and the logarithm of wind speeds are given. The linear relations are found between the spectrum levels in the frequency band from 1 to 4 kHz and the logarithm of wind speeds, which are not affected by the receiver depths. |
