“…Indeed, significant HI/DI correlations with music perception measures might be linked to the non-linguistic characteristics of both stimuli. Previous studies suggest that tests based on non-linguistic LF pitch stimuli may better estimate its significant role in music perception whilst tests with linguistic stimuli may better reflect its role in speech perception [ 28 , 29 ]. Nevertheless, the significant effects of LF pitch perception on both speech-in-noise and music perception performance become significantly evident in the overall group similarly with a previous study conducted by Fowler et al in adults [ 12 ].…”

Purpose This study aimed to investigate the effects of low frequency (LF) pitch perception on speech-in-noise and music perception performance by children with cochlear implants (CIC) and typical hearing (THC). Moreover, the relationships between speech-in-noise and music perception as well as the effects of demographic and audiological factors on present research outcomes were studied. Methods The sample consisted of 22 CIC and 20 THC (7–10 years). Harmonic intonation (HI) and disharmonic intonation (DI) tests were used to assess LF pitch perception. Speech perception in quiet (WRSq)/noise (WRSn + 10) were tested with the Italian bisyllabic words for pediatric populations. The Gordon test was used to evaluate music perception (rhythm, melody, harmony, and overall). Results CIC/THC performance comparisons for LF pitch, speech-in-noise, and all music measures except harmony revealed statistically significant differences with large effect sizes. For the CI group, HI showed statistically significant correlations with melody discrimination. Melody/total Gordon scores were significantly correlated with WRSn + 10. For the overall group, HI/DI showed significant correlations with all music perception measures and WRSn + 10. Hearing thresholds showed significant effects on HI/DI scores. Hearing thresholds and WRSn + 10 scores were significantly correlated; both revealed significant effects on all music perception scores. CI age had significant effects on WRSn + 10, harmony, and total Gordon scores (p < 0.05). Conclusion Such findings confirmed the significant effects of LF pitch perception on complex listening performance. Significant speech-in-noise and music perception correlations were as promising as results from recent studies indicating significant positive effects of music training on speech-in-noise recognition in CIC.

“…However, and despite their remarkable success at restoring speech perception, several limitations remain. Current CI users have limited pitch perception, 99 frequency resolution, 100 and dynamic range 101 . These challenges in extracting basic sound properties translate into limitations that include the ability of the user to understand speech in noisy environments, 102 locate sound sources, 103 and enjoy music 104 .…”

Increased human life expectancy, due in part to improvements in infant and childhood survival, more active lifestyles, in combination with higher patient expectations for better health outcomes, is leading to an extensive change in the number, type and manner in which health conditions are treated. Over the next decades as the global population rapidly progresses toward a super‐aging society, meeting the long‐term quality of care needs is forecast to present a major healthcare challenge. The goal is to ensure longer periods of good health, a sustained sense of well‐being, with extended periods of activity, social engagement, and productivity. To accomplish these goals, multifunctionalized interfaces are an indispensable component of next generation medical technologies. The development of more sophisticated materials and devices as well as an improved understanding of human disease is forecast to revolutionize the diagnosis and treatment of conditions ranging from osteoarthritis to Alzheimer's disease and will impact disease prevention. This review examines emerging cutting‐edge bionic materials, devices and technologies developed to advance disease prevention, and medical care and treatment in our elderly population including developments in smart bandages, cochlear implants, and the increasing role of artificial intelligence and nanorobotics in medicine.

“…Despite the huge success of CIs, there remain significant limitations for even the best-performing users ( Wilson, 2017 ), as well as substantial variation in performance between individuals ( Tamati et al, 2019 ). For example, CI users have limited pitch perception ( D’Alessandro and Mancini, 2019 ), frequency resolution ( O’Neill et al, 2019 ), and dynamic range ( Bento et al, 2005 ). These issues in extracting basic sound properties translate into limitations in real-world listening, with CI users often struggling to understand speech in challenging listening conditions ( Hazrati and Loizou, 2012 ), struggling to locate sounds ( Dorman et al, 2016 ), and having substantially reduced music appreciation ( McDermott, 2004 ; Dritsakis et al, 2017 ).…”

Cochlear implants (CIs) have been remarkably successful at restoring speech perception for severely to profoundly deaf individuals. Despite their success, several limitations remain, particularly in CI users’ ability to understand speech in noisy environments, locate sound sources, and enjoy music. A new multimodal approach has been proposed that uses haptic stimulation to provide sound information that is poorly transmitted by the implant. This augmenting of the electrical CI signal with haptic stimulation (electro-haptic stimulation; EHS) has been shown to improve speech-in-noise performance and sound localization in CI users. There is also evidence that it could enhance music perception. We review the evidence of EHS enhancement of CI listening and discuss key areas where further research is required. These include understanding the neural basis of EHS enhancement, understanding the effectiveness of EHS across different clinical populations, and the optimization of signal-processing strategies. We also discuss the significant potential for a new generation of haptic neuroprosthetic devices to aid those who cannot access hearing-assistive technology, either because of biomedical or healthcare-access issues. While significant further research and development is required, we conclude that EHS represents a promising new approach that could, in the near future, offer a non-invasive, inexpensive means of substantially improving clinical outcomes for hearing-impaired individuals.
