At your touch, the weapon rings like a struck tuning fork. The sound diminishes until it’s imperceptible, but when you touch the weapon you can feel the vibration.
(Spell Compendium, p. 59)
You empower the touched weapon with magic that causes it to emit a loud clang when it is struck against a hard surface, such as a floor, wall, or creature. The weapon deals 1d6 points of sonic damage with each successful hit, and any creature struck by the weapon must succeed on a Fortitude saving throw or be deafened for 1 minute.
