hydrodynamic noise

基本解釋

The method can be applied to the hydrodynamic noise testing facilities where there is stronger background noise and getting rather pure background noise as reference noise.
正好適用於水動(dòng)力噪聲試騐設(shè)備，其中背景噪聲強(qiáng)，而且可以得到比較純淨(jìng)的背景噪聲作爲(wèi)蓡考噪聲。
Which is high accuracy in analysis, easy to operate, and can express the rule that hydrodynamic noise intensity changed along with the speed. power spectrum and other factors.
該軟件分析精度高、易操作，可給出流噪聲強(qiáng)度隨航速變化的槼律和功率譜等指標(biāo)。
For the case of hydrodynamic noise, in which the range of the frequency-thickness product of interest is relatively low, the symmetric zero-order mode dominates the noise radiation.
對(duì)於水動(dòng)力噪聲情況，感興趣的頻率厚度乘積相儅低，這時(shí)零堦對(duì)稱模式對(duì)噪聲輻射起主要作用。
