Summary
This summary is machine-generated.Contralateral routing of signal (CROS) devices improve speech recognition in noise for unilateral cochlear implant (CI) recipients. CROS devices also enhance the quality of life for both CI users and their frequent communication partners.
Area Of Science
- Audiology
- Hearing Rehabilitation
- Biomedical Engineering
Background
- Unilateral cochlear implant (CI) users with residual hearing in the other ear lack binaural hearing benefits.
- The head shadow effect impedes speech recognition in noisy environments for these individuals.
Purpose Of The Study
- To evaluate the impact of Contralateral Routing of Signal (CROS) devices on speech recognition in noise.
- To assess the influence of CROS devices on the quality of life (QoL) for unilateral CI recipients and their frequent communication partners (FCPs).
Main Methods
- Seven adult unilateral CI recipients and their FCPs participated.
- Speech recognition testing in noise was performed with and without CROS devices.
- QoL was assessed using the APS-SSD and NCIQ for recipients and SOS-HEAR for FCPs before and after a 1-year trial.
Main Results
- Speech recognition improved by 32% when noise was directed toward the non-CI ear and speech toward the CI ear with CROS (p = .001).
- CI recipients reported significant improvements in the "general" domain of the APS-SSD.
- FCPs reported a significant reduction in hearing-related concerns.
Conclusions
- CROS devices offer significant benefits for speech recognition in noise for unilateral CI recipients.
- CROS devices positively impact the QoL of both CI recipients and their FCPs.
- CROS devices are a valuable solution for enhancing hearing and well-being in this population.
