All children use what they see and hear around them to learn about their world and to develop communication and language skills. Good hearing plays an important role in developing speech skills. Children with Down’s syndrome all have some degree of learning disability, and at birth it is impossible to tell what degree that is. Many children with Down’s syndrome also have some degree of deafness. Deafness that is not diagnosed or managed can have a negative effect on a child’s social and language development, especially if a child has a learning disability. The PDF download file at the bottom of this page explains about different types and causes of deafness, how hearing is tested, what the results of a hearing test mean, and how deafness can be managed or treated.
