“…Bimodal MCI performance was significantly better than CI-only performance, in agreement with previous studies that showed a bimodal advantage for music perception [ 5 , 10 , 11 , 13 , 19 , 46 , 47 ]. Previous studies have shown that adding low-frequency acoustic hearing in the contralateral ear can improve CI users' pitch perception ([ 46 , 48 , 49 ]). Chen et al [ 48 ] also found a significant correlation between HA experience and bimodal pitch perception in pediatric CI users, suggesting that HA experience before and/or implantation may help to develop pitch pattern perception.…”

Objective The aim of this study was to investigate the benefits of residual hair cell function for speech and music perception in bimodal pediatric Mandarin-speaking cochlear implant (CI) listeners. Design Speech and music performance was measured in 35 Mandarin-speaking pediatric CI users for unilateral (CI-only) and bimodal listening. Mandarin speech perception was measured for vowels, consonants, lexical tones, and sentences in quiet. Music perception was measured for melodic contour identification (MCI). Results Combined electric and acoustic hearing significantly improved MCI and Mandarin tone recognition performance, relative to CI-only performance. For MCI, performance was significantly better with bimodal listening for all semitone spacing conditions (p < 0.05 in all cases). For tone recognition, bimodal performance was significantly better only for tone 2 (rising; p < 0.05). There were no significant differences between CI-only and CI + HA for vowel, consonant, or sentence recognition. Conclusions The results suggest that combined electric and acoustic hearing can significantly improve perception of music and Mandarin tones in pediatric Mandarin-speaking CI patients. Music and lexical tone perception depends strongly on pitch perception, and the contralateral acoustic hearing coming from residual hair cell function provided pitch cues that are generally not well preserved in electric hearing.

“…The elements of music such as rhythm, melody, timbre and pitch are still challenging aspects for most users. In the study, 81.82% of those implanted responded that they could hear the rhythm element during music (7,8,10,14) . The instrument that most users enjoy listening to is the piano, followed by the electric guitar (16) .…”

RESUMO Objetivo Avaliar a percepção musical de adultos usuários de implante coclear, utilizando o Questionário de Música de Munique (Munich Music Questionnaire – MUMU). Métodos Pesquisa transversal, de abordagem quantitativa. Participaram do estudo 22 adultos pós-linguais, usuários de implante coclear há, pelo menos, um ano. O instrumento de coleta dos dados aplicado foi o Questionário de Munique, que abrange questões sobre a participação em atividades musicais e a respeito dos hábitos de ouvir música, em relação aos estilos musicais, aos diferentes instrumentos, ao ambiente de escuta e ao uso de dispositivos auxiliadores. Os dados foram computados em seus valores absolutos e relativos e foi utilizada estatística descritiva para caracterizar a amostra. Resultados Foi possível observar que houve melhora na frequência de música ouvida pós-implante coclear. Dos participantes, a maioria respondeu não ligar a música diretamente ao seu processador. A maioria dos pacientes mencionou que ouvia música por prazer e para relaxar e que conseguiam perceber, principalmente, o ritmo. O instrumento com maior frequência de detecção foi o piano, seguido da bateria. O gênero musical referido com grande satisfação foi música para dançar e religiosa. Dos 10 pacientes que tocavam instrumentos antes da perda auditiva, 4 voltaram a tocar após a implantação e 3, que não tocavam, começaram a tocar, após o implante coclear. Conclusão Foi possível observar que o uso do implante coclear propiciou melhora na percepção musical dos usuários, refletindo benefício na qualidade de vida. Por isso, a reabilitação deve incluir, dentro do treinamento auditivo, o desenvolvimento de habilidades musicais.

“…The immediate onset of tinnitus that occurred in 60–90% of cases in children with cochlear implants when the implants were not in use ( Van de Heyning et al, 2008 ; Chadha et al, 2009 ), may indicate that constant electrical stimulation through CIs is required to suppress ‘internal noise’ and to ‘silence’ phantom noise ( Knipper et al, 2020 ). Recalling, moreover, that CIs in children are implanted on average at the age of 1–2 years ( Peterson and Bergeson, 2015 ; Easwar et al, 2017 ), postponing the first auditory experience in these CI-carriers by 1–1.5 years ( Sharma et al, 2002 ; Petersen et al, 2015 ) might induce a delay that is too long for some maturation steps. A judgment about a critical delay of auditory experience for proper implementation of distinct developmental steps may be assessed by looking at the prevailing deficits described in congenitally deaf CI-carriers.…”

Neuronal hyperexcitability in the central auditory pathway linked to reduced inhibitory activity is associated with numerous forms of hearing loss, including noise damage, age-dependent hearing loss, and deafness, as well as tinnitus or auditory processing deficits in autism spectrum disorder (ASD). In most cases, the reduced central inhibitory activity and the accompanying hyperexcitability are interpreted as an active compensatory response to the absence of synaptic activity, linked to increased central neural gain control (increased output activity relative to reduced input). We here suggest that hyperexcitability also could be related to an immaturity or impairment of tonic inhibitory strength that typically develops in an activity-dependent process in the ascending auditory pathway with auditory experience. In these cases, high-SR auditory nerve fibers, which are critical for the shortest latencies and lowest sound thresholds, may have either not matured (possibly in congenital deafness or autism) or are dysfunctional (possibly after sudden, stressful auditory trauma or age-dependent hearing loss linked with cognitive decline). Fast auditory processing deficits can occur despite maintained basal hearing. In that case, tonic inhibitory strength is reduced in ascending auditory nuclei, and fast inhibitory parvalbumin positive interneuron (PV-IN) dendrites are diminished in auditory and frontal brain regions. This leads to deficits in central neural gain control linked to hippocampal LTP/LTD deficiencies, cognitive deficits, and unbalanced extra-hypothalamic stress control. Under these conditions, a diminished inhibitory strength may weaken local neuronal coupling to homeostatic vascular responses required for the metabolic support of auditory adjustment processes. We emphasize the need to distinguish these two states of excitatory/inhibitory imbalance in hearing disorders: (i) Under conditions of preserved fast auditory processing and sustained tonic inhibitory strength, an excitatory/inhibitory imbalance following auditory deprivation can maintain precise hearing through a memory linked, transient disinhibition that leads to enhanced spiking fidelity (central neural gain⇑) (ii) Under conditions of critically diminished fast auditory processing and reduced tonic inhibitory strength, hyperexcitability can be part of an increased synchronization over a broader frequency range, linked to reduced spiking reliability (central neural gain⇓). This latter stage mutually reinforces diminished metabolic support for auditory adjustment processes, increasing the risks for canonical dementia syndromes.
