    I have no idea where you get your "information" from, but DEWs don't typically use sound, either infra- or ultra.

    Link please.
    Or are you (yet again) going down the route of making claims but failing to support them?
    And note that both you and I used the word "typically".
    Typically sonic weapons don't fall into the category of DEW.

    What are the frequencies typically used by DEWs?

    And what's with all the anti-semitism?

    D.E.W.s is an abbreviation for Directed Energy Weapons if I'm not mistaken.
