What is ANSD?

ANSD is a hearing problem between the cochlea (organ of hearing) and the hearing nerve or with the hearing nerve itself

What can help a child with ANSD?

In children with ANSD, the ABR evaluation cannot tell us how the child hears. We will need to test your child’s hearing in the sound booth. This tells us the softest level of sound your child hears. This is called their hearing threshold. The first test can be done when a child is six months old. It may take several appointments to get this information. For some children, it takes a long time to get helpful test results.

Once we know how your child hears, we can suggest ways to help them.

For children with ANSD in one ear, there may be other suggestions. First, hearing thresholds are checked. Then, the best options for your child will be discussed.

What is best way to communicate with child with ANSD?

Audiologists and speech-language pathologists will work together to see how your child is learning to hear and talk.
