A four microphone intensity probe array has been designed and used to measure two components of the active and reactive acoustic intensity vector. The probe is also used to measure two components of the kinetic energy and the potential energy. Measurements of a point source above a reflecting plane and near the edge of two large reflecting planes were made. These results will be presented and the effects of sensor spacing, probe rotation, proximity of probe to source and boundary, and sensor phase error will be shown and the results will be compared to theoretically predicted values.
