Music perception improves in children with bilateral cochlear implants or bimodal devices

Area of Science:

• Audiology
• Neuroscience
• Music Therapy

Background:

• Pediatric cochlear implantation aims to restore hearing.
• Music perception is a complex auditory skill that can be challenging for cochlear implant users.
• Bilateral hearing and music training are potential factors influencing music perception.

Purpose of the Study:

• To assess music perception in pediatric cochlear implant users.
• To investigate the impact of bilateral hearing (bilateral cochlear implants or bimodal devices) on music perception.
• To determine the effect of music training on music perception in children with and without cochlear implants.

Main Methods:

• Utilized the Montreal Battery of Evaluation of Musical Ability test.
• Tested 26 bilateral cochlear implant users, 8 bimodal users, and 16 normal-hearing children.
• Recorded response accuracy and reaction time using an iPad application.

Main Results:

• Bilateral cochlear implant and bimodal users showed lower accuracy and slower reaction times compared to normal-hearing children.
• Music training significantly improved speed and accuracy for all participants, irrespective of hearing status.
• Reaction time improved with age, musical training duration, and residual hearing in implant users.

Conclusions:

• Bilateral cochlear implants and bimodal devices present ongoing music perception challenges for pediatric users.
• Music training is beneficial but does not fully compensate for hearing impairment and device limitations.
• Further research is needed to address music perception difficulties in pediatric cochlear implant users.
