Silence

Silence is an illusion spell that creates an area where sound is negated.

Effect
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 SR, if any. Items in a creature's possession or magic items that emit sound receive saves and SR, and unattended objects and points in space do not. This spell provides a defense against or language-based attacks, such as command, harpy song, a horn of blasting, etc.
