Casting Time: 1 standard action
Range: Long (400 ft. + 40 ft./level)
Area: 20-ft.-radius emanation centered on a creature, object, or point in space
Duration: 1 min./level (D)
Saving Throw: Will negates; see text or none (object)

Upon the casting of this spell, complete silence prevails in the affected area. All sound is stopped: Conversation is impossible, spells with verbal components cannot be cast, and no noise whatsoever issues from, enters, or passes through the area.
The spell can be cast on a point in space, but the effect is stationary unless cast on a mobile object. The spell can be centered on a creature, and the effect then radiates from the creature and moves as it moves.
An unwilling creature can attempt a Will save to negate the spell and can use spell resistance, if any. Items in a creature’s possession or magic items that emit sound receive the benefits of saves and spell resistance, but unattended objects and points in space do not. This spell provides a defense against sonic or language-based attacks, such as command, a harpy’s captivating song, a horn of blasting, and the like.
