DESCRIPTION
A translucent barrier of pure sound springs into existence. This wall is silent except for a faint hum, but bursts with discordant noise when touched by an object or creature. The wall deflects arrows, bolts, loose debris, and Small or smaller flying creatures like a wind wall spell, except these things rebound harmlessly rather than being directed upward. The burst of discordant noise deals 2d4 points of non-elemental damage to creatures within 10 feet of the triggering object or creature; touching or passing through the wall deals 2d6 points of non-elemental damage + 1 point of non-elemental damage per caster level (maximum +20). If you place the wall so that it appears where creatures are, each creature takes damage as if passing through the wall. A silence spell suppresses the wall within its area, but the wall reappears when the silence ends.
