Parametric Difference Waves for Low Frequency Acoustic Propagation

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.
