Is it Possible to Convert Sound Energy into Heat Energy?

[T.O.E Dream]

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.
