there is no such thing as sound energy. easily confirmed by looking at its unit (energy is measured in Joules)

though energy cannot be destroyed, most of it is converted into a form that is useless to us (read entrophy)

and if someone successfully come up with a way to convert any substantial amount of energy to another form at near 100% efficiency, i believe he would be in line to get a nobel prize.

sound is not a type of energy. sound is a result of vibration of a medium.

how do you generate sound? you vibrate something, this vibration (kinetic energy) pass on to the nearest particle and to the next until it reaches another surface.

think pebble as source of sound, water as air, and side of pond as your eardrums and you have a good idea.

is it logical to transfer energy by sound? considering that
1, you need a line of sight,
2, sound wave tend to spread from its source,
3, most devices are electric based, and you'd have to convert the kinetic energy back to charge

you have an extremely inefficient way of transmission
