Record-shattering underwater soundMay 17, 2019
A team of researchers has produced a record-shattering underwater sound with an intensity that eclipses that of a rocket launch. The intensity was equivalent to directing the electrical power of an entire city onto a single square meter, resulting in sound pressures above 270 decibels. The team, which included researchers from the Department of Energy’s SLAC National Accelerator Laboratory, published their findings on April 10 in Physical Review Fluids.
