  • ultrasound is understood to mean an acoustic signal beyond the upper human hearing range of around 20 kHz.
  • ultrasound propagates in the form of longitudinal waves in living tissue, with tissue particles being moved in the direction of propagation of the waves, so that there is alternating positive and negative pressure phases in the tissue.
  • the particles excited by the ultrasonic waves can emit the kinetic energy absorbed in this way in the form of heat, so that a heat treatment by means of ultrasound is made possible.

  • Tissue type In addition to warming, the alternating overpressure and underpressure phases in the tissue also cause alternating mechanical stress, which can lead to a so-called micromassage, which in turn can have desirable biological effects such as an increase in blood flow or an improvement in wound healing.
  • micromassage The health-related effects of ultrasound on living tissue depend on the type and temperature of the tissue in question. They usually only occur when a tissue-dependent characteristic sound energy is exceeded, which is commonly known as the threshold effect.
