Music Perception Testing Reveals Advantages and Continued Challenges for Children Using Bilateral Cochlear Implants.

Area of Science:

• Audiology
• Neuroscience
• Music Perception

Background:

• Music perception is complex and can be challenging for children with cochlear implants (CIs).
• Previous research indicates that instrument choice and frequency transposition can influence music perception.

Purpose of the Study:

• To assess music perception in children with bilateral CIs using a modified child's Montreal Battery of Evaluation of Amusia (cMBEA).
• To investigate if modifying instruments and transposing music frequency improves cMBEA performance in children with CIs.

Main Methods:

• A modified cMBEA with altered instrument selection and frequency-transposed trials was administered to 14 children with bilateral CIs and 23 typically hearing children.
• Results were compared to performance data from previous studies using the original cMBEA in various pediatric hearing groups.

Main Results:

• Typically hearing children scored highly on the modified cMBEA, with no significant difference from those who took the original version.
• Children with bilateral CIs showed no significant improvement on the modified cMBEA compared to previous CI cohorts.
• While a trend towards better music memory was observed in bilateral CI users compared to unilateral CI users, the effect was smaller than in prior studies.

Conclusions:

• Modifications to musical stimuli, such as instrument changes and frequency transposition, do not enhance music perception in children with bilateral CIs.
• The limitations of cochlear implant technology remain a significant factor in music perception abilities for children.
• Musical perception is influenced by instrument type and frequency, but these factors do not fully compensate for CI-related auditory processing differences.
