南海某海域环境噪声与风速相关性研究
发布时间：2019-08-11 20:08
【摘要】：针对环境噪声谱与多年前噪声谱已不同、非开阔海域环境噪声测量受限等问题,在南海某海域对环境噪声与风速进行了连续多年的观测,并对两者的关系进行了统计分析。文中首先介绍了海洋环境噪声的测量方法及风速数据的获取手段,然后针对环境噪声与风速的时变特性、相关系数进行分析,最后对比浅海与深海两种深度下环境噪声与风速相关性的差异。数据处理与分析结果表明,海洋环境噪声随风速的大小变化剧烈,7m接收深度的海洋环境噪声值与风速的相关性是所有接收深度中最好的,其中又以频率为2 000 Hz时最佳,并得到了海洋环境噪声与风速的回归拟合方程,此外浅海处环境噪声可能受到航行船舶的影响较多,浅海处环境噪声与风速的相关性明显小于深海处。
[Abstract]:In view of the fact that the environmental noise spectrum is different from the noise spectrum many years ago and the measurement of environmental noise in the non-open sea area is limited, the environmental noise and wind speed have been observed for many years in a sea area in the South China Sea, and the relationship between them is statistically analyzed. This paper first introduces the measurement method of marine environmental noise and the means of obtaining wind speed data, then analyzes the time-varying characteristics and correlation coefficients of environmental noise and wind speed, and finally compares the correlation between environmental noise and wind speed in shallow sea and deep sea. The results of data processing and analysis show that the marine environmental noise varies violently with the wind speed, and the correlation between the marine environmental noise value of 7m receiving depth and the wind speed is the best among all the receiving depths, and the regression fitting equation between the marine environmental noise and the wind speed is obtained when the frequency is 2000 Hz. In addition, the environmental noise in the shallow sea may be more affected by the sailing ship. The correlation between environmental noise and wind speed in shallow sea is obviously lower than that in deep sea.
