Digital services allow users to access and consume media content such as movies and music at any time of the day using streaming technology over internet. Cochlear implant (CI) users are also among consumers of these digital services. One of the limitations of electric hearing with CIs is the narrow available electrical dynamic range (EDR)....
No immediate practice change; findings are relevant to device signal processing engineers and could eventually inform streaming settings in future cochlear implant sound processors, but no clinician-adjustable protocol exists yet.
As cochlear implant users increasingly consume streamed media, optimising signal processing for compressed audio is a meaningful quality-of-life engineering target that bridges audiology and audio technology.
- 01Study targets the specific problem of compressed streaming audio (movies, music) sounding poor through cochlear implants.
- 02Back-end dynamic range compressors were designed and evaluated to improve listening quality.
- 03Research addresses a real-world gap between cochlear implant signal processing and modern media consumption habits.
- 04Evaluation methodology and outcome measures are detailed in the paper.
