This standard specifies the sound field characteristics and measurement methods of medical extracorporeal pressure pulse lithotripters, and the measured parameters can be used for the announcement of the acoustic output of this type of equipment. This standard applies to medical lithotripsy equipment that introduces pressure waves from the outside and focuses mechanical energy, and does not apply to percutaneous lithotripsy equipment and laser lithotripsy equipment. This standard is formulated for extracorporeal lithotripters. In other medical applications of therapeutic extracorporeal pressure pulses, this standard can also be used as a guide, as long as other specific valid standards are not involved.
