Growth & Development

Hearing

Permanent hearing loss affects approximately one to three children out of 1000. The hearing loss may affect one ear or both and may be of any degree from a mild hearing loss to complete deafness. It can be difficult to identify a child with hearing loss, particularly when the loss is relatively mild since the child may seem to respond to many sounds. Many children may also experience temporary hearing losses, particularly if they have a history of issues with congestion or ear infections. Any degree of hearing loss may have an impact on a child’s ability to learn speech and language or to hear clearly in a noisy situation but this is especially true as the severity of the hearing loss increases.
