Kolberg ER, Sheffield SW, Davis TJ, Sunderhaus LW, Gifford RH. Cochlear implant microphone location affects speech recognition in diffuse noise. Journal of the American Academy of Audiology. 2015 Jan;26(26). 51-8; quiz 109-10. PMID: 25597460 [PubMed] PMCID: PMC4446721 NIHMSID: NIHMS683865.
Despite improvements in cochlear implants (CIs), CI recipients continue to experience significant communicative difficulty in background noise. Many potential solutions have been proposed to help increase signal-to-noise ratio in noisy environments, including signal processing and external accessories. To date, however, the effect of microphone location on speech recognition in noise has focused primarily on hearing aid users.
