Sound is vibrations in ANYTHING, technically. At least, sound waves and vibration waves are almost indistinguishable one from the other, except for what humans can and can't hear due to the human ear's construction.

Theoretically, waterbenders could then "bend" sound in water, and earthbenders could "bend" sound in earth. Actually, that's pretty much what Toph does. So, yeah, it should be applicable to airbending. But it wouldn't be relegated JUST to airbending.
