From D&D Wiki
Deafening Roar [Racial]
Benefit: Benefit: When you use the Intimidate skill to demoralize your opponents, you may force all creatures within 30 feet to make a fortitude saving throw (DC 10 + 1/2 the tanreiss' character level + the tanreiss' Charisma modifier) to avoid being deafened for 1d6 + the tanreiss' Charisma modifier rounds.
Special: A fighter may select this feat as one of his fighter bonus feats.
