Abstract: An electro-acoustic device, sensitive to the size, shape and velocity of falling water drops, is described. Observations with this device suggest that the acoustic impact of drops traveling below terminal velocity may be ...

Abstract: Laboratory experiments showed that the response of the Joss-Waldvogel rainfall disdrometer, a device designed to measure raindrop size from drop impact, was influenced not only by the size and vertical velocity of the drop ...
