Does A Device Like This Exist?

Some kind of "Gun Like" device that, when pointed at an object, say a
wall of wood, and you activate the device, it "hits" the wall of wood
with some kind of concentrated wave of energy, and a bang! is heard
from the wall directly where the device was pointed (It is not touching
the wall). Or, I point the device at a glass, pull the trigger, and a
ringing sound emanates from the glass, like it's been "Hit." Would a
device that shot out concentrated, compressed sound waves work like
this? Thanks for any replies.
