Thundercone

When the caster completes the incantation and claps his hands, a cone of deafening noise is created. Creatures within the area of effect are deafened. Further, they must save vs. spell or be stunned (reeling and unable to attack) for 1-2 rounds as well. Deafened creatures receive an additional saving throw vs. spell each round, with success indicating that their hearing has returned. The spell causes no damage.
