AB  - The collision of droplets with a water surface is being actively developed in the interests of many applied problems—transfer of matter through the
ocean-atmosphere boundary, underwater acoustic noise of the marine environment, measurement of precipitation intensity, various technologies, and much
more. One of the research priorities is acoustic radiation, in particular, shock
sound arising at the moment a drop contacts the surface. The impact of the drop
is preceded by processes that affect the shape of the drop, because of which it
noticeably deviates from the spherical one. As a result, the final (contact) velocity
changes–one of the most important parameters of collision. The study of the listed
factors is carried out in this work by means of broadband acoustic measurements
and high-speed video recording.
