Sonic shower

The sonic shower was a technology that used sonic pulse vibrations to remove dirt, grime, contaminants and possibly dead skin from a humanoid body. (; , , )
== Technical information ==
Sonic showers have been in use aboard Federation starships at least as early as the 2250s, and were described as relaxing. () High-pitched sonic showers serve a similar effect as to what a "cold shower" serves. (; )
Quark once claimed that one thing that would make a Human "as nasty and violent as the most bloodthirsty Klingon" would be if they did not have access to sonic showers. ()
The technology was a means to eliminate the need for water used in bathing. However, various Starfleet vessels are still equipped with conventional water dispensing hygiene applications such as a shower or a bath tub. (; (; ; ) In 2375, the visiting Kadi Tomin could not use the sonic showers aboard the as they only washed with purified water, necessitating the installation of an ablutionary fountain in his quarters. ()
Although the technology was generally considered very effective, it did have limits on certain applications. In 2380, Commander T'Ana, a Caitian, noted that it was very difficult for sonic showers to remove cheese from fur. ()
== Components and malfunctions ==
One of the components of a sonic shower was an acoustic inverter. When an acoustic inverter broke, the sound created by the sonic shower has been described as being able to "make your hair stand on end". Another separate sonic shower malfunction aboard the was enough to shatter a nearby mirror. () When repairs were needed, a decoupler was the standard device used for checking sonic shower relays. (; ) 
Separately, sonic showers can be reprogrammed for more nefarious purposes, as was the case during Wesley Crusher's first week at Starfleet Academy, where Adam Martoni reprogrammed Crusher's sonic shower to cover him with mud. ()
One of the ways in which Benjamin Sisko occupied himself when the was on its way to Ajilon Prime in 2373 was to check the sonic shower relays. ()
== History ==
During the Occupation of Bajor, Bajoran comfort women were told to use Terok Nor's sonic showers for the Cardassians, who value cleanliness. ()
In 2364, a woman was found frozen to death by Geordi La Forge in the sonic shower aboard the with all her clothes on. ()
The sonic showers on Deep Space 9 sometimes malfunctioned. Rom and Leeta's broke down in early 2374 and Ezri Dax's needed to be repaired in late 2375. () Miles O'Brien was going to fix the latter until he became embroiled in an elaborate search – which he and Julian Bashir carried out – for a cure for a morphogenic virus. ()
In 2376, Seven of Nine canceled a singing lesson with Neelix because she felt that his vocal cords were incapable of producing basic diatonic tones and he had other rhythmic shortcomings. Neelix complained that he sounded good in the sonic shower, and Seven suggested he confine his efforts to that location. ()
