The EARS, acronym for External Auditory Receptor System, is a medical device used in the Federation to aid patients who have suffered loss of hearing. The EARS detect sound waves across the entire decibel spectrum, and transmits those signals to the brain through neural implants behind the ears of the individual via brief electrical signals that are conveyed as a burst of acoustic information. The result is a vastly different auditory acuity, with EARS-wearers able to hear in the | The EARS, acronym for External Auditory Receptor System, is a medical device used in the Federation to aid patients who have suffered loss of hearing. The EARS detect sound waves across the entire decibel spectrum, and transmits those signals to the brain through neural implants behind the ears of the individual via brief electrical signals that are conveyed as a burst of acoustic information. The result is a vastly different auditory acuity, with EARS-wearers able to hear in the ultra-low and ultra-high ranges, and beyond. | ||
==History== | |||
The EARS were developed and successfully tested by a team of Starfleet Officers on board the [[USS Paladin]], on stardate 238002.14. The three person team consisted of Lieutenant Jennifer Greene, the Chief Medical Officer, Ensign J'Kal, Assistant Chief Science Officer, and Ensign [[Hathaway, Noah|Noah Hathaway]], an Engineering Officer. | |||
During the previous mission, the crew of the Paladin were exposed to deleterious '''Negradic Radiation'''. It affected different crew members in different ways. The Chief Engineering Officer, Lieutenant [[Varaan]], had his eardrum and middle ear, including the cilia (the hair cells), deteriorate to the point of disintegration. Regenerating the lost organs was not an option, so the EARS were developed as a compensation device. | |||
==Function== | |||
Sound waves generated by mechanical forces, such as a bow being drawn across a string, water splashing on a hard surface, or air being expelled across the larynx, are received by the EARS. | Sound waves generated by mechanical forces, such as a bow being drawn across a string, water splashing on a hard surface, or air being expelled across the larynx, are received by the EARS. | ||
*Normally this procedure is accomplished by the eardrum — and, in turn, the three tiny bones of the middle ear — causing each to vibrate. The last of these three bones (the stapes, or "stirrup") jiggles a flexible layer of tissue at the base of the cochlea. This pressure sends waves rippling along the basilar membrane, stimulating some of its hair cells. These cells then send out a rapid-fire code of electrical signals about the frequency, intensity, and duration of a sound. The messages travel through auditory nerve fibers that run from the base of the hair cells to the center of the cochlea, and from there to the brain. | *Normally this procedure is accomplished by the eardrum — and, in turn, the three tiny bones of the middle ear — causing each to vibrate.
