Deaf primary school students with two cochlear implants perform much better on exams than children with only one, research from The University of Melbourne in Australia shows.
The earlier, the better
The study found that children with profound hearing loss have learned at a rate of 55-65% compared to those with normal hearing, but those given two cochlear implants early have bridged the gap. The study of children across Australia and New Zealand also revealed that the earlier the implants were fitted, the better their results would be.
“With two ears, the brain can use the auditory information from each ear to compare and process sound. With only one ear, children find learning very difficult because they tend to miss information among the constant buzz of the classroom and playground,” said Dr. Julia Sarant from the University of Melbourne’s department of audiology and speech pathology.
