Drop impact on a free surface can be followed by the entrainment of air bubbles, causing underwater sounds. It is known that there are three types of mechanisms associated with bubble sounds for the irregular bubble entrainment region. Although the first bubble sound is well recognized, relevant to the oscillation of an air bubble formed by the impact of a satellite droplet with the rising free surface, we have less knowledge about the mechanism of the second bubble sound which has often been used as the sound source of Suikinkutsu, a Japanese traditional musical instrument. In this paper we focus on exploring the mechanism of the second bubble sound due to the surface closure during the falling process of a water column into the water.
