Music Abilities and Speech Perception in Indian Pediatric Cochlear Implant Users: A Comparative Study

Area of Science:

• Audiology
• Neuroscience
• Speech and Hearing Sciences

Background:

• Cochlear implants (CI) aim to restore hearing but music perception remains a challenge for pediatric users.
• Understanding music perception in pediatric CI users is crucial for auditory rehabilitation and quality of life.

Purpose of the Study:

• To evaluate music and speech perception skills in pediatric cochlear implant (CI) recipients.
• To investigate the influence of age on music perception abilities in children with CIs.

Main Methods:

• Assessed aided word recognition using the Hindi Picture Speech Identification (PSI) test.
• Evaluated music perception with the short version of the Montreal Battery of Evaluation of Musical Abilities in Childhood (MBEMA).
• Presented computer-generated melodies and analyzed listener responses in a sound-treated room.

Main Results:

• Normal-hearing children significantly outperformed CI users across all music perception subtests (p < .001).
• Strong positive correlations were found between melody, rhythm, memory, and word recognition.
• Age did not emerge as a significant predictor of music perception skills in CI users.

Conclusions:

• Decoding music into rhythm, melody, and timbre aids understanding of CI-mediated music perception.
• Identifying specific deficits in music perception can guide therapeutic interventions for CI users.
• This study highlights areas of difficulty for implant users, informing clinical practice.
