The measurement of energy transported by bending vibration in a structure may provide useful information on the problems of vibration transmission in the structure and sound radiation from it. Measurements were performed for one-dimensional propagation of bending vibration in beams using two and four pick-ups. The errors caused by the use of finite difference approximations, differences in gain and phase among channels, and disparity in pick-up intervals were also taken into consideration. Since there have been few studies on near fields, we also investigated how far the near field extends.
