Nonlinear Acoustics: Fundamentals and Some Applications
Friday, February 5, 1993 4:00 p.m. Professor David T. Blackstock Applied Research Laboratories and Mechanical Engineering Department The University of Texas at Austin Nonlinear acoustics (also called finite-amplitude acoustics) is about very loud sound, that is, waves of very high intensity. The main difference between ordinary (small-signal) acoustics and nonlinear acoustics is in propagation speed.…
