Sensorineural hearing loss

For family education. This resource is not an individual diagnosis or treatment plan. Discuss concerns with an appropriately qualified professional.

What it means

Sensorineural hearing loss involves the inner ear's sensory structures and/or the auditory nerve. It may be present at birth or develop later, and can affect one or both ears. Communication needs vary with hearing access, family preferences, and associated health conditions.

Causes and risk factors

Possible causes include genetic conditions, congenital infections such as CMV, some birth or neonatal complications, certain medicines, and later infection or injury. Sometimes the cause remains unknown. Not all cases progress, but some do, so ongoing hearing review may be needed.

Signs and everyday impact

A child may not respond consistently to sound, miss softer or higher-pitched speech, or have speech and language concerns. Difficulty may be more noticeable in noise. Mild or one-sided loss can be easy to miss. Behavior alone cannot reliably measure the amount of hearing available.

Assessment and diagnosis

Pediatric audiology uses suitable behavioral tests, auditory brainstem response, otoacoustic emissions, and other measures as indicated. A medical evaluation may investigate cause and associated conditions. The child's communication and language access should be assessed in parallel, with attention to all relevant languages.

Treatment and therapy

Support may include hearing aids, assistive technology, and cochlear implantation for some eligible children after specialist assessment. These options do not provide identical outcomes for every child. Accessible language, including signed and/or spoken approaches chosen with informed family support, is central. Early intervention, educator support, and device follow-up help participation.

Support at home

Use the child's effective language and communication methods consistently. Check prescribed devices as instructed and make communication visible and accessible. Ask about support in noise and group settings. Families should receive balanced information and should not have to wait for a device to begin language-rich interaction.

When to seek help

Sudden or rapidly worsening hearing, new neurological symptoms, or hearing change after significant illness or injury needs prompt medical evaluation.

Questions for the care team

• Is the hearing loss stable or likely to change?
• What technology and language options suit this child?
• How will hearing and communication progress be monitored?

Terms in plain language

• Sensorineural: involving the inner ear or auditory nerve.
• Auditory brainstem response: measurement of neural responses to sound.
• Accessible language: language the child can reliably perceive and use.

Podcast preparation

Use this resource to prepare a later episode: define the topic, discuss causes and signs, explain assessment, describe treatment and home supports, then close with urgent signs and a next step.

Hearing technology alone does not replace accessible language and communication support.

Verify current clinical guidance and obtain clinical review before public recording.
