摘要
考虑航船噪声源分布的非均匀性,建立了噪声源非均匀分布的深海环境噪声模型,运用FOR3D程序3D模式,探讨深海海山对其周围的低频环境噪声场的影响。研究结果表明:海山对局部方向的环境噪声源具有明显遮挡效果,当航道区和接收点位于海山不同侧,且三者基本在一条水平连线附近时,环境噪声级明显低于平坦海底的计算值;而对于均匀分布风关噪声源,当海山范围不十分大时,海山对其周边接收点的环境噪声级并无太大影响。
Considering the distribution of ship noise sources are non-uniform, a deep sea ambient noise model is established for non-uniformly distributed noise sources. The 3D mode of FOR3 D program is applied to discuss the influence of seamount on low frequency ambient noise field. The results suggest that the seamount shades the partial noise sources obviously, when the passage and receivers are located at different sides of the seamount and the three are located at a line approximately, the noise level is obviously lower than the value for flat seabed, while the seamount will not have a great influence on the noise level for the uniform wind-generated noise sources if the seamount is not huge.
