“…In fact, Wolfe and Schafer (2008) demonstrated a highly significant 44percentage-point improvement for HINT sentence recognition in the presence of four-talker babble at 15 dB SNR using an FM system coupled to a cochlear implant sound processor for adult recipients. In a similar study, Fitzpatrick et al (2009) report significant improvement for AzBio sentence recognition in the presence of multitalker babble for adult cochlear implant users. The degree of improvement was 20.4 and 17.5 percentage points for 110 and 15 dB SNR, respectively.…”

Background Although cochlear implant patients are achieving increasingly higher levels of performance, speech perception in noise continues to be problematic. The newest generations of implant speech processors are equipped with preprocessing and/or external accessories that are purported to improve listening in noise. Most speech perception measures in the clinical setting, however, do not provide a close approximation to real-world listening environments. Purpose To assess speech perception for adult cochlear implant recipients in the presence of a realistic restaurant simulation generated by an eight-loudspeaker (R-SPACE™) array in order to determine whether commercially available preprocessing strategies and/or external accessories yield improved sentence recognition in noise. Research Design Single-subject, repeated-measures design with two groups of participants: Advanced Bionics and Cochlear Corporation recipients. Study Sample Thirty-four subjects, ranging in age from 18 to 90 yr (mean 54.5 yr), participated in this prospective study. Fourteen subjects were Advanced Bionics recipients, and 20 subjects were Cochlear Corporation recipients. Intervention Speech reception thresholds (SRTs) in semidiffuse restaurant noise originating from an eight-loudspeaker array were assessed with the subjects’ preferred listening programs as well as with the addition of either Beam™ preprocessing (Cochlear Corporation) or the T-Mic® accessory option (Advanced Bionics). Data Collection and Analysis In Experiment 1, adaptive SRTs with the Hearing in Noise Test sentences were obtained for all 34 subjects. For Cochlear Corporation recipients, SRTs were obtained with their preferred everyday listening program as well as with the addition of Focus preprocessing. For Advanced Bionics recipients, SRTs were obtained with the integrated behind-the-ear (BTE) mic as well as with the T-Mic. Statistical analysis using a repeated-measures analysis of variance (ANOVA) evaluated the effects of the preprocessing strategy or external accessory in reducing the SRT in noise. In addition, a standard t-test was run to evaluate effectiveness across manufacturer for improving the SRT in noise. In Experiment 2, 16 of the 20 Cochlear Corporation subjects were reassessed obtaining an SRT in noise using the manufacturer-suggested “Everyday,” “Noise,” and “Focus” preprocessing strategies. A repeated-measures ANOVA was employed to assess the effects of preprocessing. Results The primary findings were (i) both Noise and Focus preprocessing strategies (Cochlear Corporation) significantly improved the SRT in noise as compared to Everyday preprocessing, (ii) the T-Mic accessory option (Advanced Bionics) significantly improved the SRT as compared to the BTE mic, and (iii) Focus preprocessing and the T-Mic resulted in similar degrees of improvement that were not found to be significantly different from one another. Conclusion Options available in current cochlear implant sound processors are able to significantly improve speech understanding i...

“…The improvement of speech recognition in noise using remote microphone technology is also documented in several studies outside of the classroom (Boothroyd, 2004;Lewis et al, 2004;Fitzpatrick et al, 2009). Specifically, Lewis et al (2004) investigated the effects of remote microphone technology on speech perception in noise relative to unaided and hearing aid-only conditions.…”

“…Use of remote microphone technology has been shown to provide benefit to both adult and pediatric CI recipients as evidenced through significant improvements on measures of speech perception in noise using remote microphone technology versus a CI alone. 105,106,[112][113][114][115][116][117][118] Additionally, adult CI recipients report a perceived benefit and decreased listening effort while using remote microphone system compared with their CI alone. 113,119 While the implementation of remote microphone technology can lead to improved speech perception and auditory access to the signal of interest, the way in which the signal is delivered (i.e., coupled) to the CI can lead to more optimal benefit and improved access.…”

Specifically, the literature suggests that remote microphone technology utilizing direct input to the CI sound processor may provide a more consistent signal, resulting in better speech perception in noise, compared with soundfield, desktop, or neckloop FM systems.…”

Cochlear Implantation for Children and Adults with Severe-to-Profound Hearing Loss

Cochlear implants (CIs) have proven to be a useful treatment option for individuals with severe-to-profound hearing loss by providing improved access to one's surrounding auditory environment. CIs differ from traditional acoustic amplification by providing information to the auditory system via electrical stimulation. Both postlingually deafened adults and prelingually deafened children can benefit from a CI; however, outcomes with a CI can vary. Numerous factors can impact performance outcomes with a CI. It is important for the audiologist to understand what factors might play a role and impact performance outcomes with a CI so that they can effectively counsel the recipient and their family, as well as establish appropriate and realistic expectations with a CI. This review article will discuss the CI candidacy process, CI programming and postoperative follow-up care, as well as considerations across the lifespan that may affect performance outcomes with a CI.
