Inaudibility

The ability to become unheard by anybody or anything. Usually accompanys Invisibility.

Capabilities
Users become inaudible, usually because they can alter the air particles around them to move way apart from each other so they cannot vibrate and create sound. this power could be useful in many situations e.g sneaking past guards, hiding somewhere without anyone hearing you, creep up on someone and kill them. Sometimes users can make things around them inaudible too.
