Novel Web-Based Music Re-Engineering Software for Enhancement of Music Enjoyment Among Cochlear Implantees

Area of Science:

• Audiology
• Music Perception
• Biomedical Engineering

Background:

• Cochlear implant (CI) users often experience reduced music perception and enjoyment due to various factors.
• Existing music playback technologies may not adequately address the unique auditory processing of CI users.

Purpose of the Study:

• To investigate if patient-directed music re-engineering can enhance music enjoyment for individuals with cochlear implants.
• To identify specific audio parameters that CI users prefer when re-engineering music.

Main Methods:

• A prospective cohort study was conducted at an academic cochlear implant center.
• A multidisciplinary team developed a music re-engineering application for CI users.
• Experienced adult CI listeners re-engineered music excerpts and rated their enjoyment using a visual analog scale (VAS).

Main Results:

• User-mixed audio was rated significantly higher for enjoyment across most music genres compared to original recordings (p < 0.05).
• Re-engineered music led to increased enjoyment in 57% of participants.
• Participants preferred increased bass frequencies and reverberation, with 79% expressing interest in personalized music mixing.

Conclusions:

• Patient-directed music re-engineering effectively increases music enjoyment for cochlear implant listeners.
• Preferred adjustments include heightened bass, reverberation, and treble.
• This approach offers a viable method to improve music experience for CI users with current technology.
