The spatial distribution of the acoustic amplitude in a sonochemical cell has been numerically calculated using a finite element method taking into account the effect of vibration of the walls. The calculated results have indicated that the vibration of the walls due to the sound propagation disturbs considerably the standing-wave field inside a sonochemical cell. The glass wall disturbs a standing-wave field more than the stainless steel wall does because it vibrates more. The mode of a standing-wave acoustic field in a cell depends on the thickness of the wall. The spatial intensity distribution of sonochemiluminescence of an aqueous luminol solution agrees qualitatively with the calculated spatial distribution of acoustic amplitude in a cell.
