WebSonic Echo-Impulse Response is used for low strain integrity testing of piles and determination of deep foundation length. The Sonic Echo-Impulse Response test method (also known as the Pile Integrity Test, or PIT) is designed to determine the length and integrity of foundations when the top or part of the upper side of the foundation is … WebSonic drilling is a technique that significantly reduces friction on the drill string and drill bit by using energy resonance to affect the soil structure where it contacts the drill string. ... These steps are repeated to depth, producing a continuous core sample even through unconsolidated formations.

WebSep 5, 2007 · [1] Sonic layer depth (SLD), an important parameter in underwater acoustics, is the near surface depth of first maxima of the sound speed in the ocean. The lack of direct observations of vertical profiles of velocimeters or temperature and salinity, from which sound speed and SLD can be calculated, hampers the investigation of SLD.
