{{Main|Stoneley wave}}
A Stoneley wave is a type of boundary wave (or interface wave) that propagates along a solid-fluid boundary or, under specific conditions, also along a solid-solid boundary. Amplitudes of Stoneley waves have their maximum values at the boundary between the two contacting media and decay exponentially away from the contact. These waves can also be generated along the walls of a fluid-filled [[borehole]], being an important source of coherent noise in [[vertical seismic profile]]s (VSP) and making up the low frequency component of the source in [[sonic logging]].<ref>{{Cite web |url=http://www.glossary.oilfield.slb.com/Display.cfm?Term=Stoneley%20wave |title=Schlumberger Oilfield Glossary.

The equation for Stoneley waves was first given by Dr. Robert Stoneley (1894–1976), emeritus professor of seismology, Cambridge.<ref>{{cite journal | last = Stoneley | first = R. | title = Elastic waves at the surface of separation of two solids | journal = Proceedings of the Royal Society of London A | volume = 106 | issue = 738 | pages = 416–428 | date = October 1, 1924| doi = 10.1098/rspa.1924.0079 | bibcode = 1924RSPSA.106..416S | doi-access = free }}</ref><ref>[http://www.geolsoc.org.uk/gsl/pid/5825;jsessionid=B80DF900AFFC974028AEFB7138FB1BDF Robert Stoneley, 1929 – 2008..
