Sonic Shower

In the fictional Star Trek universe, a sonic shower is a device used for personal hygiene onboard starships, shuttlecrafts and starbases.On a Federation starship, all quarters are equipped with a sonic shower, which theoretically works by emitting high frequency sound (sonic) waves that disintegrate dirt and other substances that may be deposited on the skin.This particular piece of technology was not explored in the shows nearly as much as others, such as the transporter or the replicator, for which reason little is known about how it 'actually' works. The creators of the shows have established, however, that one of its parts is an "acoustic inverter". It has also been established that it takes several isograms of dilithium to run a sonic shower.
