Is it Possible to Convert Sound Energy into Heat Energy?

Click For Summary
Sound energy can be converted into heat energy through materials that absorb sound. This process effectively reduces sound levels, as demonstrated by mechanical sound attenuators like concrete block walls. High-intensity focused ultrasound is a relevant technology that illustrates this principle. The conversion of sound to heat is a well-established phenomenon in acoustics. Therefore, using sound-absorbing materials can significantly silence loud sounds.

Is it possible to convert sound energy into heat energy (or any other type of energy) so that a loud sound will be almost silenced?

Any material that absorbs sound turns it into heat. So you're describing any mechanical sound attenuator, such as a concrete block wall.
