摘要
基于声音分析技术,对船舶的辐射噪声进行仿真分析,给出了船舶辐射白噪声的功率谱、衰减功率谱以及周期分量线谱图,并对冲击信号曲线进行分析,给出了净化之后的船舶辐射噪声demon谱曲线等。
This article studies sound analysis technology,Simulated and analyzed the radiated noise of ships,provided the power spectrum,attenuation power spectrum,and periodic component line spectrum of the white noise radiated by ships,and analyzed the impact signal curve;provided the purified ship radiated noise demon spectrum curve.
