What this trial studies

This study evaluates an integrated program designed to enhance cochlear implant fitting and personalized auditory training for adults who are post-lingually deafened. Participants will undergo diagnostic tests and receive tailored interventions based on their individual speech recognition performance. The program includes follow-up visits and self-administered training using a mobile application over a period of approximately five months. The goal is to reduce variability in hearing outcomes and address specific error patterns in speech perception.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 who are post-lingually deafened, native Dutch speakers, and have been implanted with specific Cochlear Ltd cochlear implants for at least 12 months.

Not a fit: Patients with severe cognitive disorders, abnormally formed cochleas, or other significant health issues that affect their ability to participate may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved speech perception and overall hearing outcomes for cochlear implant recipients.

How similar studies have performed: While this approach is innovative, similar studies have shown promise in improving cochlear implant outcomes through personalized interventions.
