Radiated acoustic pressure is obtained when a free-flooded cylindrical shell of finite length is excited by a time-harmonic point force. Integral equations are formulated for an elastic thin shell with simply supported boundary condition at both ends. Near-field and far-field acoustic pressures are calculated and cases of a short shell and a long shell are discussed.
