  6. 10. Speaker that uses the non-linearity in air to create sound

    University essay from Blekinge Tekniska Högskola/Avdelningen för maskinteknik

    Author : Johan Fredin; [2005]
    Keywords : Parametric loudspeaker; Difference frequency generation; Biharmonic boundary condition; Nonlinear acoustics;

    Abstract : The aim of this work was to investigate theoretically and experimentally the fact that it is possible to create sound by using the nonlinearity in air. A speaker was built verifying the theory that if at least two high frequencies at high amplitude is propagating through a nonlinear medium, for example air, the difference frequency of these two is created in mid air.
