Gifford RH, Loiselle L, Natale S, Sheffield SW, Sunderhaus LW, S Dietrich M, Dorman MF. Speech Understanding in Noise for Adults With Cochlear Implants: Effects of Hearing Configuration, Source Location Certainty, and Head Movement. Journal of speech, language, and hearing research : JSLHR. 2018 May 17;61(61). 1306-1321. PMID: 29800361 [PubMed]
The primary purpose of this study was to assess speech understanding in quiet and in diffuse noise for adult cochlear implant (CI) recipients utilizing bimodal hearing or bilateral CIs. Our primary hypothesis was that bilateral CI recipients would demonstrate less effect of source azimuth in the bilateral CI condition due to symmetric interaural head shadow.
