Experimental results of sound transmission loss in a rangeof frequency through bubbly curtains were obtained,where the air contentwas in a wide range by means of varying pressure differences and thediameters of the pores of bubble-produce apparatus.Vibration reductionof a vessel in water due to the bubbly curtain was found.
