Summary
Continuous interleaved sampling (CIS) significantly improved speech recognition for cochlear implant users in daily life. Patients using the CIS strategy achieved their best hearing performance in years.
Area of Science:
- Audiology
- Biomedical Engineering
- Speech Processing
Background:
- Multichannel cochlear implants aim to restore hearing.
- Continuous interleaved sampling (CIS) is a sound processing strategy showing initial promise.
- Previous studies indicated immediate speech recognition benefits with CIS.
Purpose of the Study:
- To evaluate the long-term, real-world benefits of the CIS strategy.
- To assess speech recognition improvements in daily life for cochlear implant users.
- To compare CIS performance against the standard Ineraid processor.
Main Methods:
- Two Ineraid cochlear implant users participated.
- A portable processor implementing high-rate CIS was used for over 6 months.
- Speech recognition (consonant/vowel identification) and patient interviews were conducted periodically.
Main Results:
- Performance with the portable CIS processor was consistently superior or equal to laboratory findings.
- Both patients achieved their highest speech recognition scores in 6 years.
- Patients reported qualitative improvements in hearing in everyday situations.
Conclusions:
- The CIS strategy offers significant benefits for Ineraid cochlear implant users in daily life.
- Long-term use of CIS can lead to substantial improvements in hearing performance.
- CIS is a promising strategy for enhancing cochlear implant outcomes.
