Binaural listening and its effects on listening effort and development in Mandarin-speaking children with cochlear implants

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective observational study comparing school-aged Mandarin-speaking children with cochlear implants to peers with normal hearing over three years. Participants complete hearing tests and measures of listening effort, cognitive development, social skills, and quality of life at repeated visits. The study compares children using one device versus binaural listening (bilateral CIs or CI plus hearing aid) to see whether reduced listening effort links to better developmental trajectories. No experimental treatments are given; researchers observe and measure real-world hearing and developmental outcomes.
