Superhearing (Pathfinder Feat)
From D&D Wiki
Greatly enhances the ability to hear.
Prerequisite: Sight Without Seeing
Benefit: You gain a +8 bonus on listen checks. Additionally you can hear extremely well no matter the distance, the distance penalty of listen check apply only for every 100 feet of distance instead of every 10 and halves the penalties given by obstacle (such a door or stone wall). You can pick up particular sound extremely easily, negating the penalty from ambient sound (allowing you to pick up a particular voice in a very large crowd). Sadly your super hearing also cause you to take more sound-based attack, you take 150% damages from sonic damages.
Special: You may take this feat an additional time increasing the bonus to +12 and change the distance penalty of listen check apply only for every mile of distance instead of every 100 feat.
