A child’s hearing can be tested at any age and as early as a few hours after being born. In the U.S. it is estimated that 12,000 children are born each year with a hearing loss. Children also need to be screened regularly for hearing loss because it can occur any time for varied reasons. Undetected hearing loss in young children may cause difficulties in communication and learning.
Parents, caregivers, and child advocates can ask that a child’s hearing be checked whenever there is a concern. If a child is not demonstrating typical hearing milestones evaluations done by audiologists can help identify if there is hearing loss. Early diagnosis and intervention can help with language, listening and speech.
The following hearing milestones were developed by the John Tracy Clinic, a nonprofit in Los Angeles, CA providing parent-centered services to young children with hearing loss.
