Study on measurement of sound attenuation coefficient in bubble wake by pool [PDF]

open access: yesE3S Web of Conferences, 2020
In this paper, bubbles are generated by controlling the air inlet volume of the ceramic tube array with a gas divider valve. Stimulation tests of sound attenuation characteristics of the wake of bubbles in a laboratory pool are performed.
