Plouf is the noise made by the impact of a solid sphere into a pool when air is entrained. In fact, this impact does not always entrained air and our first point is to address the criterion of entrainement. When air is entrained, a cavity is created the dynamics of which can be described by a Rayleigh-Plesset approach. We show that an algebric equation exists to describe the dynamic of this cavity up to the pinching.
