The energy may be acoustic, pressure waves, you've probably heard of LRAD devices (or long-range acoustic devices) -- devices they've discussed in the press -- so ultrasound is one mode that could be used for this. We also could have radiofrequency. We could have microwave. We could have light -- lasers are an example of it. I'm going through these just as examples, i want to make it eminently clear that we don't know what they were exposed to and certainly can't make any inferences as to whether it was deliberate or inadvertent.

The way we view this is that it's an area for active research, i'm currently doing some research sponsored by the Office of Naval Research, where we're looking at using computer simulation and a variety of physical and biological models to just get an idea of what are likely possibilities.
