Absorption of acoustic energy converts energy into what form?

Explanation:
Absorption turns the acoustic energy into heat. When ultrasound passes through tissue, some energy is absorbed rather than reflected or scattered. That absorbed energy is dissipated as thermal energy due to viscous losses and molecular friction, causing a small rise in temperature. Microbubbles relate to contrast agents and involve mechanical interactions rather than a general energy conversion, decibels measure level of sound, not a form of energy, and while the wave can induce tissue motion, the energy specifically absorbed is what becomes heat.
