Types and Causes of Hearing Loss
Not all hearing loss is the same — and the type you have determines the best way to treat it. Here's a clear breakdown.
Conductive Hearing Loss
Sound is blocked from reaching the inner ear — by earwax impaction, fluid, infection, or a problem in the ear canal or middle ear. Often temporary and treatable, sometimes medically reversible.
Sensorineural Hearing Loss
Damage to the tiny hair cells (stereocilia) of the inner ear or the auditory nerve — the most common type. Usually permanent, but extremely treatable with the right hearing aids.
Mixed Hearing Loss
A combination of both conductive and sensorineural hearing loss. Treatment often involves addressing the conductive component medically, then treating the sensorineural component with hearing aids.
Common Causes of Hearing Loss
- Aging (presbycusis)
- Noise exposure (85 dB+ — concerts, firearms, machinery)
- Genetics / congenital factors
- Earwax & blockages
- Ear infections
- Ototoxic medications
- Head trauma
- Certain illnesses
Which Causes Are Reversible?
Conductive causes like earwax impaction are often reversible. Sensorineural loss is managed, not cured — but it is treated successfully every day with modern hearing technology. The only way to know for sure is to get a professional evaluation.
