“…All subjects had been fitted with the HiRes Optima (Sequential) sound processing strategy and an input dynamic range of 80 dB on their everyday processors. Program parameters were set according to the FOX target driven, computer-assisted approach described in Govaerts et al [ 14 , 15 , 16 ].…”

Roger is a digital adaptive multi-channel remote microphone technology that wirelessly transmits a speaker’s voice directly to a hearing instrument or cochlear implant sound processor. Frequency hopping between channels, in combination with repeated broadcast, avoids interference issues that have limited earlier generation FM systems. This study evaluated the benefit of the Roger Pen transmitter microphone in a multiple talker network (MTN) for cochlear implant users in a simulated noisy conversation setting. Twelve post-lingually deafened adult Advanced Bionics CII/HiRes 90K recipients were recruited. Subjects used a Naida CI Q70 processor with integrated Roger 17 receiver. The test environment simulated four people having a meal in a noisy restaurant, one the CI user (listener), and three companions (talkers) talking non-simultaneously in a diffuse field of multi-talker babble. Speech reception thresholds (SRTs) were determined without the Roger Pen, with one Roger Pen, and with three Roger Pens in an MTN. Using three Roger Pens in an MTN improved the SRT by 14.8 dB over using no Roger Pen, and by 13.1 dB over using a single Roger Pen (p < 0.0001). The Roger Pen in an MTN provided statistically and clinically significant improvement in speech perception in noise for Advanced Bionics cochlear implant recipients. The integrated Roger 17 receiver made it easy for users of the Naida CI Q70 processor to take advantage of the Roger system. The listening advantage and ease of use should encourage more clinicians to recommend and fit Roger in adult cochlear implant patients.

“…Clinical studies have shown that FOX was successful in systematically improving the results of the psychoacoustic test outcomes (audiometric thresholds, A §E phoneme discrimination, A §E loudness scaling, speech audiogram), especially in the first few months after switch on (Vaerenberg et al, 2011(Vaerenberg et al, , 2014a. A prospective multicenter randomized controlled trial showed that the speech audiometric results 6 months after switch-on with a target-driven, FOX-assisted approach was equivalent to or better than a conventional manual approach (Battmer et al, 2015). Even in long-term and well-fitted subjects, FOX has improved the measurable outcomes in seven out of 10 cases (Buechner et al, 2014).…”

Persons with long-term CI use, who received a FOX-assisted CI fitting at least 6 months ago, display improved speech understanding after MAP modifications, as recommended by the current version of FOX. This can be explained only by intrinsic improvements in FOX's algorithms, as they have resulted from learning. This learning is an inherent feature of artificial intelligence and it may yield measurable benefit in speech understanding even in long-term CI recipients.

“…A literature review found no other studies that assessed recipient set stimulation levels and its impact on performance outcome measures. The only other more non-traditional method of CI fittings reviewed in the literature was Battmer et al (29). The “Fitting to Outcomes eXpert” (FOX), employed by The Eargroup (Antwerp, Belgium).…”

“…Battmer et al (29), investigated speech understanding and fitting times in a group of patients activated with FOX versus a standard clinical activation. Unfortunately, the groups were poorly matched for duration of deafness and a direct comparison for speech outcomes could not be completed.…”

Objective To determine whether patient-derived programming of one’s cochlear implant (CI) stimulation levels may affect performance outcomes. Background Increases in patient population, device complexity, outcome expectations, and clinician responsibility have demonstrated the necessity for improved clinical efficiency. Methods Eighteen postlingually deafened adult CI recipients (mean=53 years; range, 24–83 years) participated in a repeated-measures, within-participant study designed to compare their baseline listening program to an experimental program they created. Results No significant group differences in aided sound-field thresholds, monosyllabic word recognition, speech understanding in quiet, speech understanding in noise, nor spectral modulation detection (SMD) were observed (p>0.05). Four ears (17%) improved with the experimental program for speech presented at 45 dB SPL and two ears (9%) performed worse. Six ears (27.3%) improved significantly with the self-fit program at +10 dB signal-to-noise ratio (SNR) and four ears (26.6%) improved in speech understanding at +5 dB SNR. No individual scored significantly worse when speech was presented in quiet at 60 dB SPL or in any of the noise conditions tested. All but one participant opted to keep at least one of the self-fitting programs at the completion of this study. Participants viewed the process of creating their program more favorably (t=2.11, p=0.012) and thought creating the program was easier than the traditional fitting methodology (t=2.12, p=0.003). Average time to create the self-fit program was 10 minutes, 10 seconds (mean=9:22; range, 4:46–24:40). Conclusions Allowing experienced adult CI recipients to set their own stimulation levels without clinical guidance is not detrimental to success.
