title: The investigation of localized sound generation using two ultrasound beams.
abstract: A quantitative analysis of the effects of difference frequency, source separation, and crossing angle on the generated scattered difference frequency sound fields is presented to evaluate the feasibility of localized sound production using 2 uniform pistons. Nonlinear crossed beam experiments were also carried out in an anechoic chamber. Experimental results show that the audible sound could be generated within the interaction region defined by the overlap volume of 2 ultrasonic beams.
