What is sensorineural hearing loss?

Sensorineural hearing loss (SNHL) is generally caused by the loss of hair cells in the inner ear. This loss can be the result of a viral infection, an immune system malfunction, an inflammatory injury to the ear, or blocked blood flow to the ear. It can also be caused by sudden or long term exposure to loud noise.

If you think you may be experiencing symptoms of sensorineural hearing loss (SNHL), there are some tell-tale signs you can look out for. These include:

Symptoms of SNHL can occur in one ear (unilateral), both ears (bilateral) or can occur in both ears but be worse in one (asymmetrical). If you're experiencing sensorineural hearing loss, a hearing test can establish the extent of hearing loss and help you find the treatment path that's right for you.

While sensorineural hearing loss most often occurs over time, in rarer cases, it can also come on suddenly. This is referred to as sudden sensorineural hearing loss (SSNHL) and, to increase chances of restored hearing, should be looked at immediately.

SSNHL tends to occur in your 50s or 60s, but can happen at any age and can usually be treated if caught early! It may start with a loud pop in the ear or you might feel like your ears are clogged. Your hearing will gradually decline within a matter of hours and the window for successful treatment usually falls between 10 to 14 days. If you believe you may be experiencing sudden sensorineural hearing loss, contact your Hearing Care Professional immediately.
