RADIATED NOISE LEVEL的意思|示意

A theory and method for calculating the noise level radiated by plate are presented in this paper.

本文提出了一种计算平板结构辐射噪声的理论和方法。

The source level of the ship-radiated noise is estimated by analyzing the measurement records from passage ship noise.

通过对实测舰船数据分析估计舰船辐射噪声的总声源级。

The first part is about the features extraction, including the estimation of source level of the ship-radiated noise and the line extraction of the rotation frequency of propeller noise spectrum.

首先是舰船辐射噪声特征量的提取，包括舰船总声源级的估计和螺旋桨轴频线谱的提取。
