You create a barrier of sonic energy at a distance of 10 feet from yourself which follows your movement. Creatures on either side of the barrier hear it as a loud but harmless buzzing. Nonmagical sound does not cross the barrier. Supernatural or spell-based sounds or sonic effects penetrate the barrier only if the caster or originator of the effect succeeds on a caster level check (DC 11 + your caster level). A creature that crosses the barrier takes 1d6 points of non-elemental damage +1 point per caster level (maximum +20) and must make a Fortitude save or be Deafened for 1 minute. The sonic vibrations create a 20% miss chance for any missiles (including siege weapon attacks) crossing the barrier in either direction.
Deafened: A deafened character cannot hear. He takes a –4 penalty on initiative checks, automatically fails Perception checks based on sound, takes a –4 penalty on opposed Perception checks, and has a 20% chance of spell failure when casting spells with verbal components. Characters who remain deafened for a long time grow accustomed to these drawbacks and can overcome some of them.
