An attempt was made to determine the presence of scattering resulting from the nonlinear interaction of two finite‐amplitude sources, operating in water. Experiments were performed with two beams crossed at right angles and also in the nonperpendicular case, A detector crystal, tuned to the summation frequency (13.4 Mc) of the two sources (7.4 Mc and 6.0 Mc), and pivoted about a point above the interaction region, was used to investigate the scattered field. The results indicated no scattered sound above the noise level of the detection system. The lack of scattered sound is in agreement with the theoretical considerations of Westervelt, but is contrary to the predictions of Ingard and Pridmore‐Brown.
