Types of hearing loss: Conductive, sensorineural and mixed — and what each means

Types of hearing loss: Conductive, sensorineural and mixed — and what each means

There are three types of hearing loss: conductive (sound can't travel properly through the outer or middle ear), sensorineural (the inner ear or hearing nerve is affected) and mixed (both at once). The type matters more than the amount, because it decides the treatment pathway — some conductive losses are medically treatable, while sensorineural loss is usually permanent but manages well with hearing aids. A hearing assessment identifies your type and degree in a single appointment. This guide explains each type, the degrees of loss, and where each pathway leads. For what triggers hearing loss in the first place, see what causes hearing loss; for the warning signs, see the early signs of hearing loss.

What is conductive hearing loss?

A mechanical problem: sound is blocked or dampened on its way to a healthy inner ear. Common culprits are wax blockages, fluid behind the eardrum, ear infections, a perforated eardrum, or stiffening of the middle-ear bones (otosclerosis). Sounds seem muffled or distant, and your own voice can sound boomy. The important news: many conductive losses are temporary or medically treatable — wax can be removed, infections treated, fluid resolved, and some middle-ear conditions corrected surgically. This is why testing matters early: conductive hearing loss is the type you least want to leave undiagnosed, because some of it is fixable.

What is sensorineural hearing loss?

Damage to the delicate hair cells of the cochlea or to the hearing nerve — the type behind most adult hearing loss, including age-related change and noise damage. It usually develops gradually, affects high pitches first, and makes speech sound mumbled rather than quiet, especially in background noise. Sensorineural loss is generally permanent: the hair cells don't regrow. Management, not cure, is the honest framing — and modern management is good. Well-fitted hearing aids help many people with mild to severe loss hear more clearly in everyday listening situations, though individual benefit varies. Read more in our sensorineural hearing loss guide.

What is mixed hearing loss?

Both at once — for example, an older adult with age-related sensorineural loss who also develops a middle-ear problem. The conductive part may be treatable while the sensorineural part is managed with amplification. Mixed losses are exactly why the diagnostic sequence (otoscopy, air- and bone-conduction audiometry, tympanometry) matters: each test isolates one part of the system, so the treatable component doesn't get missed.

What do the degrees of hearing loss mean? Mild, moderate, severe and profound

Alongside type, your audiogram shows degree — how far thresholds have shifted:

Degree can differ between ears and across pitches — most age- and noise-related losses hit high frequencies hardest, which is why "I hear, but I don't understand" is such a common description.

How is each type of hearing loss treated? Hearing aids, amplification and medical care

The pathway follows the diagnosis:

1. Conductive — medical or surgical treatment first where possible: wax removal (we examine and refer to an appropriate provider), GP or ENT care for infection, fluid or structural problems. Residual loss can then be supported with amplification.
2. Sensorineural — hearing aids are the primary management for most people, matched to your audiogram and lifestyle and adjusted over follow-up visits. For losses beyond hearing aid benefit, cochlear implant candidacy is assessed through specialist services.
3. Mixed — treat the treatable component, manage the rest. Sequencing is decided case by case with your GP or ENT where needed.

Whatever the type, tinnitus commonly travels with it — our tinnitus treatment options guide covers management approaches.

When should you get a hearing assessment and diagnosis?

If hearing has changed — even subtly — the type is worth knowing, because waiting only helps if the problem is one that fixes itself, and you can't know that without looking. A comprehensive hearing assessment at Hearingcare in Caloundra identifies type and degree in about an hour, with results explained in plain English the same day by Linda Whittaker, Qualified Audiometrist. Sudden hearing loss in one ear is the exception to "book when convenient": treat it as urgent and see your GP or an emergency department promptly.
