This spell changes the volume of sounds created close to its center of effect. The caster moves his hand in a circular motion at the point he wants to center the spell. With the uttering of a command word, the area so outlined begins to glow softly. The outlined area is disk-shaped and can be as small as 2 inches in diameter or as large as 1 foot in diameter.
The disk acts as a sound magnifier: Whatever sound enters the active (caster) side of it may exit the other side at a much different volume. The volume can be increased or decreased at the casters mental command: up to five times louder, or softer, than normal.
The material component is a small cone of paper.
