Hearing

The auditory sense determines a creature’s capacity for perceiving vibrations in air. It’s possible for an ear to receive vibrations through other substances, but that media must be placed near to or in direct contact with the ear (ex. through water or solid substances like stone). Described below are the different types of the auditory sense. Unless otherwise noted, a creature has normal hearing.

Normal Hearing - Like a typical human’s hearing, normal hearing ranges between 50 hz and 18000 hz (depending on the individual).

Superior Hearing - A creature with Superior Hearing is able to perceive fine details in sound and is able to locate the source of sounds in a three-dimensional environment. Creatures with Superior Hearing gain a +2 Racial bonus to Listen checks and Awareness.

Inferior Hearing - A creature with Inferior Hearing can perceive basic sounds and generally cannot perceive the location of that sound in three-dimensional space. Creatures with Inferior Hearing suffer a -2 penalty to Listen checks and Awareness.

Special Forms of Hearing

Blindsense - Blindsense is a powerful form of hearing that allows a creature to determine the shape of its environment through sound waves (i.e. echolocation). It works in all directions simultaneously, so it can be very difficult to sneak up on a creature with blindsense. Blindsense can be used to establish Line of Perception and grants a +2 Racial bonus to Listen checks and Awareness.

Hearing controls the Sensory Skill Listen.
