The guard’s eyes widen, and he yells for help—uselessly.

The subject cannot be heard by anyone else for the duration of the spell. This only affects noises directly created by the subject, such as speaking or striking something with a held object.

Thrown objects and other “secondary” noises can still be heard;  a sorcerer could cast a fireball silently, but the explosion would be fully audible.

On a successful save, the effect lasts for only 1d4+1 rounds.
