The use of vector sound-intensity probes for locating sound sources is a relatively undeveloped area. In a prior presentation [Hickling et al., J. Acoust. Soc. Am. 93, 2357 (A) (1993)] it was shown experimentally that the direction of a single source in water could be detected within (plus or minus)2 deg using a probe with four pressure transducers. It was also known that the effect of noise interference from another source could be removed by spectral subtraction. In the present presentation, numerical continuation methods are used to solve a set of nonlinear equations to determine the coordinates and strength of two uncorrelated sound sources from measurements with two vector probes.
