Speech recognition was evaluated for ten adults with normal hearing and eight adults with Nucleus cochlear implants (CIs) at several different signal-to-noise ratios (SNRs) and with three frequency modulated (FM) system arrangements: desktop, body worn, and miniature direct connect. Participants were asked to repeat Hearing in Noise Test (HINT) sentences presented with speech noise in a classroom setting and percent correct word repetition was determined. Performance was evaluated for both normal-hearing and CI participants with the desktop soundfield system. In addition, speech recognition for the CI participants was evaluated using two FM systems electrically coupled to their speech processors. When comparing the desktop sound field and the No-FM condition, only the listeners with normal hearing made significant improvements in speech recognition in noise. When comparing the performance across the three FM conditions for the CI listeners, the two electrically coupled FM systems resulted in significantly greater improvements in speech recognition in noise relative to the desktop soundfield system.

Se evaluó el reconocimiento del lenguaje en diez adultos con audición normal y en ocho adultos con implantes cocleares (IC) Nucleus, a diferentes tasas de relación señal/ruido (SNR) y con tres tipos de sistemas FM: de escritorio, de uso corporal y de conexión directa en miniatura. Se le pidió a los participantes que repitieran frases del HINT presentadas con ruido de lenguaje en un ambiente de clase, y se determinó el porcentaje correcto de repetición de palabras. Se evaluó el desempeño tanto de los participantes normo-oyentes como de aquellos con CI, usando el sistema de campo sonoro de escritorio. Además, el reconocimiento del lenguaje para los participantes con CI fue evaluado usando dos sistemas FM acoplados eléctricamente a sus procesadores de lenguaje. Cuando se comparó el campo sonoro de escritorio con las condiciones No-FM, sólo aquellos con audición normal lograron mejorías significativas en el reconocimiento del lenguaje en medio de ruido. Cuando se comparó el desempeño en las tres condiciones FM para los sujetos con CI, los dos sistemas FM acoplados eléctricamente aportaron una mejoría significativamente mayor en el reconocimiento del lenguaje en ruido, con relación al sistema de campo sonoro de escritorio.
