A statistical theory is presented for the stationary and nonstationary response of a system of multispanned beams and a system of multispanned panels under noise excitation. The intermediate supports of the beam and panel systems are, respectively, elastic springs and elastic stringers. The matrices of frequency response functions are obtained from the transfer matrices which represent the mechanism that transmits the displacements and forces at one location of the system to another. The effects of the structural and acoustic dampings and of the acoustic apparent mass are accounted for in the formulation. Author
