Officially, there isn't any but soundbending could be a subskill (Aang amplified his voice in the Sun Temple and when he uses the bison whistle he technically airbends. Also, Aang detected Combustion Man by the deep breath sound transmitted through the air.). Nonetheless, airbending is already powerful yet it could have even more potential force.
