Cochlear Implant Sound Quality Ratings for Speech and Music

A study of 11 adults with unilateral MED-EL cochlear implants compared sound quality matches for speech and music. Participants rated similarity on a scale of 1 to 10, with speech matches averaging 9.3 and music matches averaging 6.7. Stephen R. Dennison authored the research, which was last updated on April 9, 2026.

Use Cases

• Analyze differences in sound quality perception between speech and music based on similarity ratings.
• Investigate the effectiveness of specific audio manipulations (e.g., bandpass filtering, pitch shifts) for matching CI sound quality.
• Compare a digital audio workstation methodology against custom software for generating acoustic approximations.
• Study individual variability in sound quality matching requirements across participants.

Strengths

• Includes specific average similarity ratings: 9.3 for speech and 6.7 for music.
• Describes the methodology used, involving 11 participants with unilateral MED-EL CIs.
• Compares results from a digital audio workstation to previous custom software.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (61.6 KB), indicating limited scope.
