Combined Electric and Acoustic Hearing (EAS) in Children and Adults

MI-összefoglaló

A vizsgálat saját részvételi feltételeiből. Gép olvasta ki az oldalon álló regiszterszövegből, ezért tévedhet. Hogy ki vehet részt, azt a lenti regiszterszöveg és a vizsgálat csapata dönti el.

The trial is looking for children and adults who use a cochlear implant (CI) and still have some low-pitch natural hearing in both ears. It is also looking for children and adults with normal hearing to compare with.

Életkor

5 years and older. Children aged 5 to 17 years and adults aged 18+ years.

Nem

All sexes can join.

A betegség stádiuma

People with a CI need at least one CI and mild to severe sensorineural (inner ear) hearing loss in both ears. Without aids, hearing thresholds must be 80 dB HL or less at 125 and 250 Hz in both ears. People with normal hearing can also join.

Korábbi kezelés

People in the CI groups must already have at least 1 cochlear implant. They must be willing to use combined electric and acoustic hearing (EAS) in the implanted ear(s). This is checked with data from the device software.

A részvétel fő kizáró okai

Mit akar kideríteni a vizsgálat

Cochlear implants are surgically implanted devices which restore the ability to hear to the hearing impaired. Improvements in surgery and electrodes have results in an increased number of adults and children who have residual hearing and can benefit from electric and acoustic hearing in the same ear. This is called Electric Acoustic Stimulation (EAS). Many studies have shown that adult EAS users show significant benefits for speech understanding in noise and spatial hearing tasks as compared to a CI paired only with a contralateral HA. Even though this type of hearing is becoming more common, there is limited research on how it can be beneficial to children with CIs. The benefits of this study are a greater understanding of the participant's speech understanding, binaural processing, and spatial hearing. The results will help audiologists and researcher better understand how cochlear implants work, specifically when using electric and acoustic hearing in the same ear.
