Abstract
A method is described for using acoustic waves to hold an object in position against wandering in any direction, by the use of a single transducer. Formulas are provided for levitating an object along an axis of a rectangular or cylindrical chamber or the center of a spherical chamber. The formulas take into account the relative volume of the object to the chamber.
