    TITLE:
    Prametric Difference Waves for Low Frequency Acoustic Propagation

    ABSTRACT/BENEFITS:

    Prior research indicates that an array of ultrasonic sources operated
    with an offset in frequency will produce infrasonic or very low
    frequency energy. This energy is useful because it is omni-directional,
    and it propagates well with little absorption. With sufficient energy,
    the resulting infrasonic waves can be disabling or lethal. Synetics
    proposes an approach toward developing infrasonic waves that can
    ultimately be incorporated into future man-portable small arms weapon
    systems. This approach utilizes modernized pneumatic technology which
    produces an extremely high-powered ultrasonic source. The resulting
    frequency generated is precisely controlled such that the desired high
    power infrasound frequency can be generated at the target by beating two
    focused ultrasonic sources.

    BENEFITS:

    The potential post applications of the parametric difference wave
    generator include non-lethal crowd control, non-lethal self defense
    units for police and personal use, and soot and crustacean removal
    devices for commercial industries.
