摘要：针对工程应用中对舰船辐射噪声信号仿真结果在听觉感受上模拟度欠佳的问题，建立了一种基于音色
参量谱质心的辐射噪声仿真方法。采用基于实测谱的连续谱仿真模拟，并且通过整体对比实测信号的听觉特
性来搜索符合特征样本音色的线谱族幅值参量，在一定程度上改善了仿真信号的听觉特征。通过仿真最优匹
配度趋势来寻求最优搜索次数，用以缩短仿真时间，得到了符合工程应用的结果。

Abstract: Aiming at the problem that the simulation results of ship radiated noise signal in engineering
application are not good enough in auditory perception, a method of radiated noise simulation based on the
centroid of tone parameter spectrum is established. By using the continuous spectrum simulation based on
the measured spectrum, and by comparing the acoustic characteristics of the measured signal, the amplitude
parameters of the line spectrum family matching the timbre of the characteristic samples are searched, which
improves the auditory characteristics of the simulated signal to some extent. By simulating the trend of the
optimal matching degree, the optimal search times are sought to shorten the simulation time and get the results
in line with the engineering application.
Keywords: : Radiation noise; Spectral centroid; Optimal matching degree
