【摘要】：針對(duì)環(huán)境噪聲譜與多年前噪聲譜已不同、非開(kāi)闊海域環(huán)境噪聲測(cè)量受限等問(wèn)題,在南海某海域?qū)Νh(huán)境噪聲與風(fēng)速進(jìn)行了連續(xù)多年的觀測(cè),并對(duì)兩者的關(guān)系進(jìn)行了統(tǒng)計(jì)分析。文中首先介紹了海洋環(huán)境噪聲的測(cè)量方法及風(fēng)速數(shù)據(jù)的獲取手段,然后針對(duì)環(huán)境噪聲與風(fēng)速的時(shí)變特性、相關(guān)系數(shù)進(jìn)行分析,最后對(duì)比淺海與深海兩種深度下環(huán)境噪聲與風(fēng)速相關(guān)性的差異。數(shù)據(jù)處理與分析結(jié)果表明,海洋環(huán)境噪聲隨風(fēng)速的大小變化劇烈,7m接收深度的海洋環(huán)境噪聲值與風(fēng)速的相關(guān)性是所有接收深度中最好的,其中又以頻率為2 000 Hz時(shí)最佳,并得到了海洋環(huán)境噪聲與風(fēng)速的回歸擬合方程,此外淺海處環(huán)境噪聲可能受到航行船舶的影響較多,淺海處環(huán)境噪聲與風(fēng)速的相關(guān)性明顯小于深海處。
[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.
