One treatment for kidney stones is extracorporeal shock wave lithotripsy (ESWL). ESWL uses sound waves to create strong vibrations (shock waves) that break the stones into tiny pieces that can be passed in the patient's urine. The procedure lasts about 45 to 60 minutes and can cause moderate pain, so sedation is often used.
Some kidney stone patients who couldn't afford ESWL exposed themselves to rap music at extremely high sound pressure levels instead. This had no effect on their kidney stones, but it destroyed their brains, so they no longer felt pain, or anything else.
