First seen Jun 27, 2026 ยท Last updated Jun 27, 2026

Summary

This study looked at whether a cochlear implant in the deaf ear helps adults who have good hearing in one ear but severe hearing loss in the other. 59 adults received an implant and were tested on understanding speech in quiet and noise, locating sounds, and overall benefit. The goal was to see if adding the implant improves hearing beyond using the better ear alone.
