The ASHA Leader, a publication of the American Speech-Language-Hearing Association - February 16, 2010 ---------------- Bilateral Cochlear Implants Are Two Ears Better Than One? cite as: Litovsky, R. (2010, February 16). Bilateral Cochlear Implants : Are Two Ears Better Than One?. The ASHA Leader. by Ruth Litovsky "Listen carefully and tell me where the sound is coming from," I explained to "Emma," a 12-year-old, bilateral cochlear implant user whose second CI had recently been activated. "What do you mean by 'where'?" Emma asked. "When I hear sounds, they are in my head or very near my ear." The experience of Emma (not her real name) is typical of tens of thousands of unilateral cochlear implant (CI) users, who generally do not experience spatial hearing. For these individuals, the spatial auditory world often collapses into the head rather than being perceived at external locations. Unilateral CIs provide children the opportunity to attain spoken language, and offer adults renewed access to a hearing world. However, the lack of input to both ears can be a challenge. In the spring of 2002, Emma embarked on a journey experienced by few children at that time when she became one of the first children in the United States to receive a second CI. When pediatric bilateral CIs were first provided, the candidates typically were children between 5 and 12 years of age who already had attained notable success with their first CI. By participating in research at the Binaural Hearing and Speech Lab in Madison, Wis., Emma and her cohort of pioneer pediatric bilateral CI users contributed to a growing body of knowledge about the emergence of spatial hearing skills in this population. Prior research had focused on communication milestones and the importance of the age of implantation (for the first- and typically only-implanted ear); this new line of research was aimed at determining whether bilateral implantation would provide measurable, significant benefits on tasks required for functioning in complex multi-source auditory environments. ...................
