Your critical hits cause enemies to lose their hearing.

Prerequisites: Base attack bonus +13, Critical Focus.

Benefit: Whenever you score a critical hit against an opponent, the victim is permanently deafened. A successful Fortitude save reduces the deafness to 1 round. The DC of this Fortitude save is equal to 10 + your base attack bonus. This feat has no effect on deaf creatures. This deafness can be cured by esuna, or similar abilities.
