| 中文摘要: |
The local special feature of underwater ambient noise in the northern Huanghai sea has been investigated.The results obtained from the analysis of data measured for six days and nights have shown that the time-varying characterization of ambient noise spectrum level is remarkable and its fluctuation at every analyzed frequency band presents an equiform periodicity varying with time synchronously.The dependence of average ambient sea noise spectrum level on logarithmic wind speed within the middle range (16-30 knot) appears in "V" form.
The current Crouch's conclusion (1972) has been developed by us to be a mathematical model based on the segment correlation regression.Using this model to describe and expain the characterization of local ambient sea noise is available. |
