  3. Kidney stones and sound waves.... on Sonic Torpedo Defense · · Score: 5, Interesting

    Actually, being an acoustician, I would be willing to bet that they would use a phased array of loudspeakers. With the correct phasing of the speakers, some pre-determined "point" in the water could be driven to very high sound pressure levels, while the remaining ambient noise, while still loud, may not be all that dangerous. This would occur as a transient excitation from the various loudspeakers propagates away from the source and coalesces at the point in the water where the torpedo is located, the point where a very large pressure spike is generated. There are plenty of smart researchers in the navy and I have my doubts that they would use anything other than a phased array. And by the way, this is the same methodology that they use to destroy kidney stones.
