Expert Answer:
When sound hits a medium, part of it is reflected and most of it gets absorbed by the medium.
This absorbed sound creates acoustic vibrations of the molecules inside the medium. These vibrations produce heat inside the medium obeying the kinetic theory which says that a vibrating molecule of a medium produces heat of a particular temperature.
More the vibrations, higher is the temperature of the material.
