Absorption of acoustic energy results in which form?

Explanation:
Absorption converts acoustic energy into heat in the tissue. When the ultrasound wave propagates, part of the energy is absorbed by the tissue due to viscous and thermal losses, causing a small rise in temperature—the thermal effect of ultrasound. Microbubbles are used as contrast agents and are not the form in which absorbed energy is stored. Kinetic energy would imply bulk motion, which isn’t the primary result of absorption in this context. Decibels are just a unit for measuring sound intensity or attenuation, not a form of energy. So heat is the correct form produced by absorption.
