To solve the problem that the physical noise sources of small generator and its sensitivity can't be obtained directly,the empirical mode decomposition(EMD)and support vector machine(SVM)were combined to separate the blind sources of noise signals,obtain the independent components(IC)and identify the physical noise sources.The SVM regression model was established on the samples of sound pressure level of measuring point,generator power and sound pressure level of the IC.The sensitivity calculation function ...
