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.
