Ok, so I know that Iraq and the US are using sound based weapons with infrasound and ultrasound and all those other sound things to use as biological weapons (ie making them think God is talking to them, having them experience pain through the bursting of the eardrum, thing like that) However is it physically possibe using real science, or theoretically possible (not comic book science) to use sound vibrations in the way the character Shriek from Batman Beyond used them? To create effective earthquakes with them? making molecules move so much that the vibrations cause things to explode? all the other parts to his powers as well.....any of the smart people have an answer?

Demonstrated Infrasonic weapon
The U.S. DOD has demonstrated phased arrays of infrasonic emitters. The weapon, about the size of a truck, usually consists of a device that generates sound at about 7Hz. The output from the device is routed (by pipes) to an array of open emitters, which are usually one wavelength apart. At this frequency, armor and concrete walls and other common building materials vibrate, and therefore provide no defense. The frequency is chosen to be near the resonant frequency of internal organs, causing illness, deafness, and internal injuries.
As a defense to such a weapon, mechanical "diode walls" to convert the oscillating air into a steady flow have been demonstrated. Although not common at this time, they could be mass-produced and would provide an effective countermeasure.
Lethal sonic weapons, in air:
Most of these are science fiction only. There are these types:
* Powerful low-pitched sound waves as a shock wave that blows enemies back. Fictional rifles that project sound to knock down or stun are featured in the 2002 movie Minority Report.
* A tight beam of focused sound used as a weapon like the focused light in laser guns.
* A powerful ultrasound beam which can liquefy living tissue.
* A powerful sound designed to get buildings or structures to resonate and cause them to collapse.
Lethal sonic weapons, underwater:
Underwater, some sonic weapons are practicable in the real world. For an example, see anti-frogman techniques.
* Ultrasound disintegration of solids in liquids is well known in industry, and could be adapted into a weapon.
* It has long been known that ultrasound in water will kill small water animals.
* There have been unconfirmed reports of scuba diver deaths and mass deaths of fish from being caught in powerful undersea ultrasound beams used by navies for communicating with submarines.
* It is suspected that sperm whales and dolphins use powerful ultrasound to stun or kill their prey.
* There have been unconfirmed speculations about development of lethal underwater ultrasound anti-frogman weapons.
