Cochlear implants are electronic devices that help those with severe hearing loss to process sounds.
Dutch researchers studied 30 children with the devices.
They found that those with one implant enjoyed improved speech, hearing and quality of life after getting a second implant for the other ear.
Perhaps the biggest help is that they were better able to hear speech in a crowded area like a classroom.
Details are in the journal Archives of Otolaryngology -- Head & Neck Surgery.
