Scientists create sound so loud it can boil water

American scientists have created an underwater sound so loud that it instantly boils water and could even rupture person's heart and lungs, if heard outside of an aquatic surrounding. Stanford scientists directed small blasts of water at powerful X-rays that instantly vaporized the surrounding water, resulting in a shockwave. A train of shockwaves followed and once the threshold for how intense underwater sound can get was crossed, the water then formed small bubbles, which quickly decayed. The sound pressure exceeded 270 decibels, louder than a rocket launch at takeoff, Cnet reports.
