Found this on a subaru site, sounds fairly logical to me.
"I think its a radar/laser jammer; not an electronic kind, instead a physical kind. Since sound waves are compressions and expansions of the medium that they travel through, I would imagine this device has the power to change the index of refraction of the air either directly infront of it, or if its tied into the chassis, the air around the car with infrasonic waves. This would mean that incoming photons (laser, radar) would have "zig zag" through the different indicates of refraction as they are traveling to, and bouncing away, from the car, slightly increasing the distance they have to travel and/or curving them (literally) away from the car. Kinda like a force field.
What does this mean? A radar/laser gun assumes that the speed of light in the detecting medium is constant...and it is, assuming constant density. This device might change the density of that medium (air) oh so slightly so that it throws range finders/speed detectors out of whack by varying that constant. Think heat shimmer on the roof of a car, on a sunny day. Hot air immediately over searing metal is less dense than the cooler air far from it, so light gets "bent" as it passes through that area en route to your eye. This device does something similar, changing the density of the air with sound waves, like a bomb blast shock wave or LOUD sub woofer."
