Acoustic Emissions Associated with Drop Impacts

Abstract

When a liquid drop falling through the air strikes a flat horizontal surface there are acoustic emissions associated with this impact in both the air and the liquid. Under certain conditions, a small air bubble can be entrained in the liquid by the impacting drop and stimulated into volume pulsations that radiate quite strongly. When several drops impact the surface in a short time interval, as in rainfall, the acoustic emissions associated with the drops can be a major contribution to the total acoustic emission over a considerable bandwidth. This paper demonstrates that the major portion of the acoustic emission associated with rainfall is probably not due to the direct impact of the drop with the surface but is primarily due to volume pulsations of gas bubbles entrained in the liquid by the impacting drop.
