Extraction of Modal Parameters from Structural Acoustical Responses

A method to identify modal parameters from structural acoustical signals was proposed by a combination of empirical model decomposition (EMD) and stochastic subspace identification (SSI). Firstly, several intrinsic mode functions (IMF) were obtained with EMD, then the data obtained from the EMD was...
