“…This limited number of electrode contacts takes over the task of the IHC and the frequency discrimination is accordingly poor compared to the natural hearing sensation. [6][7][8] For example, hearing perception of CI-treated patients is hindered in the event of multiple speakers or in order to perceive complex sounds such as music. 9 To improve frequency discrimination, the number of electrode contacts should be increased.…”

CitationDirecting neuronal cell growth on implant material surfaces by microstructuring. 2012, 100 (4) Abstract: For best hearing sensation, electrodes of auditory prosthesis must have an optimal electrical contact to the respective neuronal cells. To improve the electrode-nerve interface, microstructuring of implant surfaces could guide neuronal cells toward the electrode contact. To this end, femtosecond laser ablation was used to generate linear microgrooves on the two currently relevant cochlear implant materials, silicone elastomer and platinum. Silicone surfaces were structured by two different methods, either directly, by laser ablation or indirectly, by imprinting using laser-microstructured molds. The influence of surface structuring on neurite outgrowth was investigated utilizing a neuronal-like cell line and primary auditory neurons. The pheochromocytoma cell line PC-12 and primary spiral ganglion cells were cultured on microstructured auditory implant materials. The orientation of neurite outgrowth relative to the microgrooves was determined. Both cell types showed a preferred orientation in parallel to the microstructures on both, platinum and on molded silicone elastomer. Interestingly, microstructures generated by direct laser ablation of silicone did not influence the orientation of either cell type. This shows that differences in the manufacturing procedures can affect the ability of microstructured implant surfaces to guide the growth of neurites. This is of particular importance for clinical applications, since the molding technique represents a reproducible, economic, and commercially feasible manufacturing procedure for the microstructured silicone surfaces of medical implants.

“…This finding both supports and extends upon previous literature that has shown that imitation is problematic for children with hearing loss (Chin et al, 2012;Cleary et al, 2002;Dillon et al, 2004;Ertmer & Goffman, 2011;Ertmer et al, 1997;Nakata et al, 2012;Peng et al, 2008;Sehgal et al, 1998). For example, children with hearing loss have been shown to have difficulty producing exact imitations of non-words, and their attempted repetitions tended to have fewer syllables as compared to the target (Cleary et al, 2002;Dillon et al, 2004).…”

“…Previous studies suggest that imitation abilities are negatively affected in infants with HI (Chin, Bergeson, & Phan, 2012;Dillon, Cleary, Pisoni, & Carter, 2004;Ertmer & Goffman, 2011;Ertmer, Kirk, Sehgal, Riley, & Osberger, 1997;Nakata, Trehub, & Kanda, 2012;Peng, Tomblin, & Turner, 2008;Sehgal, Kirk, Svirsky, Ertmer, & Osberger, 1998). While there is very little past research that investigates naturalistic vocal imitation in hearing impaired infants, there are several studies that looked at imitative abilities of older children with cochlear implants (CIs) by using both non-word and whole word repetition tasks in laboratory settings.…”

Vocal matching, the ability to imitate phonetic properties of speech, was examined in spontaneous interactions of sixteen dyads of mothers and their hearingimpaired (HI) infants with cochlear implants and age-matched normal-hearing (NH) infants. Mother-infant dyads came to three sessions at three, six, and 12 months postimplantation. Vocal matching was defined as an instance of perceptual and acoustic similarity of vowels and consonants between adjacent maternal and infant utterances.Vocal matching occurred in 25% to 50% of infant and in 17% to 64% of mother vocalizations across dyads. Both mothers and infants in the HI group produced fewer matches as compared to the NH group. However, the number of matches increased in both groups over the period of three testing sessions. These results suggest that vocal matching is a part of interactions between mothers and their HI infants and that pediatric hearing loss affects both infants' and mothers' imitative abilities.

“…Also, the perception of prosody is generally poorer in CI users compared to normalhearing listeners (e.g., Holt and McDermott, 2013;Holt et al, 2016;Marx et al, 2015;Meister et al, 2009Meister et al, , 2011Morris et al, 2013;Peng et al, 2008Peng et al, , 2009. Although the temporal envelope of speech carries information related to duration, pauses, and amplitude, the reduced spectral and temporal resolution in CI listening (e.g., Oxenham and Kreft, 2014) negatively impact the perception of prosody.…”

Low-frequency fine-structure cues allow for the online use of lexical stress during spoken-word recognition in spectrally degraded speech

English listeners use suprasegmental cues to lexical stress during spoken-word recognition. Prosodic cues are, however, less salient in spectrally degraded speech, as provided by cochlear implants. The present study examined how spectral degradation with and without low-frequency fine-structure information affects normal-hearing listeners' ability to benefit from suprasegmental cues to lexical stress in online spoken-word recognition. To simulate electric hearing, an eight-channel vocoder spectrally degraded the stimuli while preserving temporal envelope information. Additional lowpass-filtered speech was presented to the opposite ear to simulate bimodal hearing. Using a visual world paradigm, listeners' eye fixations to four printed words (target, competitor, two distractors) were tracked, while hearing a word. The target and competitor overlapped segmentally in their first two syllables but mismatched suprasegmentally in their first syllables, as the initial syllable received primary stress in one word and secondary stress in the other (e.g., "'admiral," ""admi'ration"). In the vocoder-only condition, listeners were unable to use lexical stress to recognize targets before segmental information disambiguated them from competitors. With additional lowpass-filtered speech, however, listeners efficiently processed prosodic information to speed up online word recognition. Low-frequency fine-structure cues in simulated bimodal hearing allowed listeners to benefit from suprasegmental cues to lexical stress during word recognition.
