“…On the other hand, the Naída CI processor was highly preferred in general, for its design and also for its performance, which is enhanced by the new front-end features available. 12,13 With the large number of features and options available on the Naída CI, it could have been expected to contribute to increased difficulty in counselling recipients. However, counselling was found to be equivalent to the Harmony.…”

“…They include an adaptive beamformer option called UltraZoom, which improves hearing performance in noisy conditions, specifically when speech is coming from the front and Binaural VoiceStream Technology™. 12,13 Many implant candidates now receive bilateral implants and Binaural VoiceStream Technology on the Naída CI provides wireless transmission of data between devices, allowing bilateral cochlear implant users to synchronize hearing across the two ears. 14 DuoPhone and ZoomControl deliver the signal picked up on one side of the head, to the contralateral ear and QuickSync allows for easy, instant and simultaneous adjustments of volume and program settings on both Naída CI sound processors by adjusting the settings on only one sound processor.…”

The aim of this survey was to gather data from both implant recipients and professionals on the ease of use of the Naída CI Q70 (Naída CI) sound processor from Advanced Bionics and on the usefulness of the new functions and features available. A secondary objective was to investigate fitting practices with the new processor.A comprehensive user satisfaction survey was conducted in a total of 186 subjects from 24 centres. In parallel, 23 professional questionnaires were collected from 11 centres.Overall, there was high satisfaction with the Naída CI processor from adults, children, experienced and new CI users as well as from professionals. The Naída CI processor was shown as being easy to use by all ages of recipients and by professionals. The majority of experienced CI users rated the Naída CI processor as being similar or better than their previous processor in all areas surveyed. The Naída CI was recommended by the professionals for fitting in all populations. Features like UltraZoom, ZoomControl and DuoPhone would not be fitted to very young children in contrast to adults.Positive ratings were obtained for ease of use, comfort and usefulness of the new functions and features of the Naída CI sound processor. Seventy-seven percent of the experienced CI users rated the new processor as being better than their previous sound processor from a general point of view. The survey also showed that fitting practices were influenced by the age of the user.

“…Most CI recipients complain about difficulty understanding speech in noise at signal-to-noise ratios (SNRs) that would have little impact on speech understanding in listeners with normal hearing (Gifford and Revit, 2010). Present day devices are equipped with directional microphones and signal processing algorithms that can result in improved speech perception in difficult listening environments (Geibler et al, 2015;Mauger et al, 2014). However, the improvements in speech perception offered by these advances remain poorer than what listeners with normal hearing would achieve under similar listening conditions, especially when signal and noise are co-located in space (Gifford and Revit, 2010).…”

Cochlear implant (CI) recipients have difficulty understanding speech in noise even at moderate signal-to-noise ratios. Knowing the mechanisms they use to understand speech in noise may facilitate the search for better speech processing algorithms. In the present study, a computational model is used to assess whether CI users' vowel identification in noise can be explained by formant frequency cues (F1 and F2). Vowel identification was tested with 12 unilateral CI users in quiet and in noise. Formant cues were measured from vowels in each condition, specific to each subject's speech processor. Noise distorted the location of vowels in the F2 vs F1 plane in comparison to quiet. The best fit model to subjects' data in quiet produced model predictions in noise that were within 8% of actual scores on average. Predictions in noise were much better when assuming that subjects used a priori knowledge regarding how formant information is degraded in noise (experiment 1). However, the model's best fit to subjects' confusion matrices in noise was worse than in quiet, suggesting that CI users utilize formant cues to identify vowels in noise, but to a different extent than how they identify vowels in quiet (experiment 2).

“…Directional microphones and dual-microphone technologies also can improve speech understanding in noise for implant users. AB's T-Mic and UltraZoom and Cochlear's zoom and BEAM microphone technologies provide noticeable benefit for listening to a speaker directly in front of the listener in a noisy environment (Geissler et al, 2015;Gifford and Revit, 2010;Mauger et al, 2014;Wolfe et al, 2012).…”

Evaluation of Speech Recognition of Cochlear Implant Recipients Using Adaptive, Digital Remote Microphone Technology and a Speech Enhancement Sound Processing Algorithm

ClearVoice and Roger technology each improves speech recognition in noise, particularly when used at the same time. Because ClearVoice does not degrade performance in quiet settings, clinicians should consider recommending ClearVoice for routine, full-time use for AB implant recipients. Roger should be used in all instances in which remote microphone technology may assist the user in understanding speech in the presence of noise.

Speech reception threshold benefits in cochlear implant users with an adaptive beamformer in real life situations

Abstract: When tested in challenging and realistic noise environments, the Naida CI UltraZoom adaptive beamformer resulted in significantly lower mean SRTs than when the T-Mic alone was used.
