42 children (4 to 13 years old), divided into 2 groups: experimental group - composed of 21 children using unilateral CI, exposed to musical activities; and control group - 21 children with normal hearing, not exposed to musical activities. |
Experimental group: subdivided into 2, comprising 8 children exposed to home musical activities once or twice a week e.g., singing, playing a musical instrument, or other musical activity, such as music appreciation (listening); and 9 children exposed to music classes weekly. Musical activities were evaluated through questionnaires addressed to parents and daycare center/school staff. The 42 children were assessed twice with standardized protocols over 16 months: digit test, prosody, duration pattern discrimination, intensity, and fundamental frequency. |
To investigate prosodic perception in early implanted children concerning auditory discrimination, auditory working memory, and exposure to music. |
There was an improvement in the prosodic perception of participants who had music classes and musical activities at home. Children with CI who were exposed to music performed statistically equivalent to the control group, except in the digit test. |

20 children aged 9 to 13 years divided into two groups: experimental group - 11 children with hearing impairment (6 used unilateral CI and 5 bilateral hearing aids) and control group - 9 children with typical hearing development. |
All children participated in a weekly lunchtime music club at school, consisting of 45 minutes of class for 1 year, with vocal games, integration of auditory, visual, and kinesthetic learning modes, and other musical learning approaches, such as the Kodály method. Standardized tests were used to assess pitch discrimination, rhythm, and timbre recognition administered 4 times over 1 year. |
To determine a baseline for the performance of hearing-impaired children on standardized musical perception tests (rhythm, pitch, and timbre) and determine whether exposure to structured music would have an effect on musical perception. |
The results highlight the importance of temporal cues for musical perception. There was no correlation between test performance and music club participation. However, teachers reported that participation improved children's confidence, social development, and engagement in music lessons generally. |

18 children and adolescents using CI, aged 6 to 15 years, divided into two groups: experimental group - 9 children exposed to music classes. Control group - 9 children exposed to art classes. |
9 children were exposed to musical training (piano lessons, singing, and other musical approaches): 5 with unilateral CI and 4 with bilateral CI. 9 children were exposed to art classes (painting): 4 with unilateral CI and 5 with bilateral CI. The training period was 6 months for both groups. Measures were taken before during and after training to evaluate musical perception (Montreal Battery for Evaluation of Amusia - MBEA) and emotional prosody of speech: identification of the emotional intention of a semantically neutral sentence under audio-only and audiovisual conditions. |
To evaluate whether children using CI obtain similar benefits when exposed to musical training. |
The results showed that musical training improved the perception of music elements and the emotional prosody of speech. The group exposed to visual artistic activities did not improve these skills. |

50 children aged 6 to 18 years: 16 with typical hearing development, 26 bilateral CI users, and 8 with bimodal adaptation (CI + hearing aid). Divided into two groups: an experimental group - exposed to musical activities; and a control group - not exposed to musical activities. |
The experimental group was exposed to music theory classes, instrumental practice of at least one non-percussive instrument, and singing lessons. |
To verify whether musical perception correlates the benefits of music classes with the development of auditory and musical perception. Tests were used to analyze the perception of discrimination of similar melodies, changes in pitch, rhythm, and memorization. |
They concluded that children who participated in musical training were faster and more accurate in perceiving music, regardless of their hearing condition. |

10 children using unilateral and bilateral CI aged 5 to 10 years, divided into two groups for evaluation. |
The children were exposed to 16 weeks of morphosyntactic training (similar to speech therapy training), including 8 sessions with computerized musical interventions (rhythmic training) and 8 with morphosyntactic training. Pre- and post-training measures: performance tests in receptive syntactic processing with morphosyntactic tests (grammatical judgment and syntactic comprehension), nonword repetition, visuospatial attention, and memory. |
To propose a long-term training program to improve the syntactic processing of children using CIs. |
Musical activities improved performance in syntax comprehension, grammatical judgment, and repetition of nonwords in musical training. Effects were observed for attention tasks, especially fast and accurate sequential analysis, but not for memory tasks. |

43 children divided into two groups: experimental group - 21 children using unilateral CI, aged 4 to 13 years. Control group - 22 children with typical hearing development. |
12 children in a group exposed to musical interventions, such as singing lessons, and 9 not undergoing musical interventions. Measurements: a) computerized tests to evaluate perception and recognition of words, timbre, and intensity, throughout 14 to 17 months. b) brain responses in the mismatch negativity (MMN) and P3a-evoked potential (ERP). ERP 75 minutes, including placement and removal of the EEG cap. The behavioral experimental session took 30 to 45 minutes. |
To evaluate how children with CI who sing informally develop in the perception of speech in noise compared to those who do not sing. |
Speech perception in children using CIs improved mainly due to tests with longer intervals of grade changes. The results suggest that singing and playing musical instruments may have the potential to improve speech perception in noise in children with CI. |

18 children divided into two groups: 10 children using unilateral CI, aged 7 to 13 years. 8 children with typical hearing, matched for age. |
Children using CI had 21 months of formal musical training before starting choir rehearsals, for 2 weeks rehearsing just one song for 3 hours a week plus 1 hour of training at home. The children in the other group were not exposed to musical training, only choir rehearsal. Measurements: after 2 weeks of rehearsal, all children recorded a file with the music rehearsed with voice only, without accompaniment. Acoustic and metrics were analyzed to quantify tuning accuracy and musical performance. |
To assess the singing proficiency of children using CIs. |
Choir members with CI demonstrated high accuracy in pitch and time measurements and performance similar to children with typical hearing. They concluded that well-directed musical activities can be an effective strategy for developing oral skills, including the use of the singing voice, for post-implantation CI users. |
