The acoustic field resulted by the radiation of sound from vibrating structure is predicted based on the sound pressure measurements. The sound pressures are measured at discreate point on the measurement plane; Hologram. Based on these discreate measurements, the sound field away from the acoustic source is constructed based on the discreate form of Kirchhoff-Helmholtz integral equations. The velocities, intensities, and pressures of arbitrary plane of interests in space are predicted and the acoustic field is visualized. The effects on the sound field reconstruction; finite aperture effect, effect of finite sampling interval in space are studied in terms of wraparound error and spatial aliasing. Numerical simulations and experimental verifications are performed to see these effects. To reduce the wraparound error, zero padding technique in space is used and the usefulness of the method is demonstrated by various examples.
