What causes hearing loss in children?

Hearing loss in children can arise from many causes, and it can be present at birth (congenital) or develop during childhood (acquired). Some causes are temporary and treatable, while others are longer lasting. Identifying the cause early is important because good hearing supports speech, language and learning in the early years.

What causes hearing loss present from birth?

Congenital hearing loss may be linked to factors such as:

• Genetic or hereditary factors, sometimes with no family history
• Complications during pregnancy or around the time of birth, including prematurity or low birth weight
• Certain infections during pregnancy
• Lack of oxygen or jaundice needing treatment around birth

In Australia, the Healthy Hearing newborn screening program checks babies' hearing soon after birth, which helps identify hearing loss early so support can begin promptly.

What causes hearing loss that develops later?

Acquired hearing loss in childhood can result from:

• Middle-ear infections (otitis media) and glue ear: fluid behind the eardrum is very common in young children and often reduces hearing temporarily
• Other infections such as measles, mumps or meningitis
• Earwax build-up causing blockage
• Loud noise exposure, including personal audio at high volume
• Head injury or certain medications

Glue ear in particular is a frequent cause and often improves on its own, though it sometimes needs medical management.

What signs might parents notice?

Signs vary with age but can include not startling at loud sounds as a baby, delayed speech, not responding to their name, turning the television up loud, seeming inattentive, or struggling at school. Because children may not realise they are missing sounds, changes are often noticed by parents or teachers first. Recurrent ear infections are also worth mentioning to your GP.

Can some childhood hearing loss be prevented or reduced?

Not every cause can be avoided, particularly those present from birth or linked to genetics. But some everyday risks can be lowered with sensible habits, which is worth knowing as a parent:

• Treat ear infections promptly: having recurrent infections and glue ear reviewed by a GP helps limit periods of reduced hearing.
• Manage noise exposure: keep personal audio at a comfortable level, use volume limits on devices, and provide ear protection at loud events.
• Keep up with immunisations: vaccination reduces the risk of infections such as measles, mumps and meningitis in childhood.
• Attend routine checks: newborn screening and follow-up appointments help pick up changes early.
• Support ear health after swimming or colds: mention any lingering blockage or discharge to your GP.

None of these steps guarantee an outcome, but together they support healthy hearing during the important early years. If ear infections are frequent or you have any concern at all, it is worth raising it with your GP or an audiologist rather than waiting to see if things improve on their own.

Why does early detection matter?

The early years are crucial for developing speech and language, so identifying and supporting hearing loss early can make a meaningful difference to a child's development and schooling. Support depends on the cause and may involve medical treatment, monitoring, or devices, coordinated with your GP, an ENT specialist and services such as Hearing Australia for children.
