If you wake up and notice your hearing is different, you may have Sudden Sensorineural Hearing Loss (SSNHL).

What is sudden hearing loss?

Sudden Sensorineural Hearing Loss (SSNHL) is a rapid, unexplained hearing loss, typically in one ear, occurring within 72 hours.  

It is considered an urgent medical emergency and treatment (within 48-72 hours) can significantly improve recovery chances and prevent permanent hearing damage.

What are the symptoms of sudden hearing loss?

People who have experienced sudden hearing loss often describe it as waking up and feeling as though their ear has been “switched off.” Some of the most common symptoms can include:

• Loss of hearing in one ear (rarely both)
• A sensation of fullness or pressure in the ear
• Feeling like you have an earwax buildup or ear infection
• Tinnitus (ringing or buzzing sounds)
• Vertigo or dizziness
• Difficulty understanding speech in noisy environments

What can I do if I have sudden hearing loss?

Sudden hearing loss is considered an urgent medical emergency. If you notice a sudden drop in hearing, contact your GP immediately. They will typically refer you for an urgent audiology test and, if SSNHL is confirmed, to an ENT (Ear, Nose, and Throat) specialist. Treatment (usually oral or intratympanic steroids) is often initiated quickly due to the urgency.
