This study follows. to the author's former theoretical study on method for estimation of bubble density distribution by acoustic attenuation. The remaining problems are discussed for the realization of real time indication system of bubble distribution, such as the maximum acoustic pressure for linear vibration and building-up time of vibration. Under. these conditions, experiments to measure bubble density distribution functions both photographically and acoustically were carried out using bubble generator. Results were compared with each other and it was found that coincidence of these results were very good. Thus, the acoustic attenuation method was verified to be good for bubble distribution measurement.
