✦ Synopsis

This paper presents a study of the free and forced interior acoustic response of a "nite uniform cylindrical shell. The cross-section of the shell is a square with rounded corners. Conformal mapping is used to map the physical domain onto a circular cylindrical domain. The acoustic response is obtained in the circular domain by using the Rayleigh}Ritz method in conjunction with a variational principle. Numerical simulation results are presented showing the mode shapes and the forced pressure distribution at various frequencies.

The impulse response approach to evaluate time dependent pressures resulting from the specified velocity of a baffled piston is used to investigate the time dependent far field pressures radiated from a circular piston. The far field pressures are expressed as the convolution of the velocity of the
