Acoustical measurements of air bubbles bursting at a water surface: Bursting bubbles as Helmholtz resonators

Evidence is presented that air bubbles bursting at the surface of water are Helmholtz resonators. The detection by an acoustic transducer of the aerosols generated by the collapsing bubble is also demonstrated. The use of this detector to measure such parameters as bubble collapse time, the number and spacing of the jet drops, their ejection velocities, and their size is discussed.
