Friday, February 20, 2009 4:00 p.m. RLM 7.104 Professor David T. Blackstock Department of Mechanical Engineering and Applied Research Laboratories The University of Texas at Austin http://www.me.utexas.edu When two intense primary sounds of different frequencies propagate together, their nonlinear interaction produces various distortion components. Particularly interesting is the difference frequency component, which is at the…
