Cochlear implant (CI) users typically report that speech recognition becomes substantially more difficult in the presence of background noise. This perception is consistent with objective measures showing CI require favorable signal-to-noise ratios than normal-hearing (NH) listeners to achieve equivalent recognition. However, recent research hearing aid suggests noise tolerance or "willingness listen noise" may also influence perceived communication ability. Therefore, purpose this study was evaluate extent which and predict ability among adult users.Twenty were evaluated on an test (Bamford-Kowal-Bench Sentences Noise [BKB-SIN] test) a measure (Acceptable Level [ANL] completed self-report difficulty (Abbreviated Profile Hearing Aid Benefit [APHAB]). Relationships between BKB-SIN scores, ANL aided APHAB scores for ease communication, noise, reverberation, Global scales assessed. In addition, compared control group 23 NH listeners.CI demonstrated poorer listeners, as expected; however, their similar those listeners. not systematically related one another. Each accounted third variance users' scores; together, two 72% variance.Both are strongly associated self-perceived The seem reflect different factors individual's experience; thus, both provide useful clinical information. establishment formal criteria predictive excessive help identify who could benefit from additional audiologic rehabilitation.
