The ridges that make up the outer ear, or pinna, amplify the sound waves and passes them to 6 sets of canals and eardrums thus splitting the sound waves into 6 distinct frequency ranges. The vibration from the ear drums are sent to 6 cochleas which convert them to nerve impulses and transmitted to an enlarged temporal lobe.  Also unique to other species, there is no degenerative hearing loss.

The Kerelian voice consists of sounds made by the vocal folds (cords), muscles of the larynx, and size of the vocal tract. Its frequency ranges from about 10 to 42,000 Hz, 6 times greater than other humanoids.  The lungs pump air into the larynx which vibrates 2 sets of vocal folds (Kerelians are the only race to have two) producing 2 different sets of frequencies. The frequencies are sent to a complex set of microscopic tubes and valves that can selectively add or subtract the frequencies resulting in incredible range. The muscles of the larynx adjust the length and tension of the vocal folds to ‘fine tune’ pitch and tone.

To live in a low pressure/oxygen atmosphere Kerelians have developed larger than normal lungs and heart. Efficient anaerobic and aerobic systems manage how oxygen is delivered to key organs and muscles. A mini organ called an Ebra augments the production of red blood cells. Kerelians have two kidneys and two lungs and need both of each to survive. In the case of disease or injury the body can survive with one until a new one regenerated. This process takes 2-4 weeks and in the interim a prosthetic is used.

The brain is not divided into hemispheres.  It consist of 4 lobes. The temporal lobe is the largest and most complex.  It is responsible for processing audio information and a large portion, the Euadin, is used solely as a "back up" memory node for the other lobes. In case of injury to a lobe, information stored in that area can be retrieved from the Euadin later on preventing memory loss. An area in the Temporal lobe, the Zyfur area, is only active in about 15 percent of Kerelians who are born empathic, either E1 or E2 on the [[T/E Rating System|Telepathic/Empathic Scale]]. It is still a mystery to why this is so. There is no genetic evidence that emphatic abilities are inherited.  Kerelian neurologists theorize a gene is mutated while the fetus is developing.
