The Three Types of Hearing Loss
There are many different contributing factors to hearing loss, but it’s generally agreed that there are three types of hearing loss. Designating which type is affecting you or your loved one depends on the location of the damage.
- Conductive hearing loss is caused by problems in the ear canal, ear drum or middle ear due to infection, allergies, perforation, earwax or malformations
- How it Works: Sound isn’t properly conducted through the outer ear canal to the eardrum and middle ear
- What it Causes: Usually a reduction in perceived volume or ability to pick up on quieter sounds
- Possible Corrections: Medical or surgical correction possible
- Sensorineural hearing loss is caused by problems in the inner ear due to loud noise, head trauma, disease, hereditary causes, aging or malformations
- How it Works: Hair cell malfunction and nerve damage disrupting the ability to pick up on sounds
- What it Causes: Usually a reduction in ability to pick up on quieter sounds or even normal-volume speech or sounds
- Possible Corrections: Medical or surgical correction not usually possible
- Mixed hearing loss is a combination of conductive and sensorineural loss caused by damage in the outer, middle or inner ear or auditory nerve
It’s important to know the causes and types of hearing loss in order to know the treatments and tools at your disposal.
