Types of Hearing Loss: Conductive, Mixed & Sensorineural Explained
By Audiotone Hearing Clinics | KPHB Colony, Kukatpally, Hyderabad | Updated September 2026 | 9 min read
Quick answer: Hearing loss falls into three main categories — Conductive Hearing Loss (a problem in the outer or middle ear), Sensorineural Hearing Loss (damage to the inner ear or auditory nerve), and Mixed Hearing Loss (a combination of both). The right treatment depends on which type you have, confirmed through a hearing test at Audiotone Hearing Clinics, KPHB Colony, Kukatpally.
How Hearing Loss Is Classified
Audiologists classify hearing loss by where in the hearing pathway the problem occurs — the outer/middle ear, the inner ear, or both. This classification matters because it determines whether the condition can be medically treated, managed with hearing aids, or requires a combination of care. Below, we cover the three main types in the order they're most commonly diagnosed.
1. Conductive Hearing Loss
Conductive hearing loss occurs when sound waves are blocked or reduced on their way through the outer ear canal or middle ear, before they ever reach the inner ear. The inner ear itself usually works normally — the issue is mechanical.
Common Causes
- Earwax (cerumen) buildup blocking the ear canal
- Fluid behind the eardrum from an ear infection
- A perforated or scarred eardrum
- Otosclerosis (abnormal bone growth in the middle ear)
- Structural issues present from birth
Typical Symptoms
- Sounds seem muffled or quieter than usual
- Your own voice may sound louder or different ("occlusion effect")
- Ear pain, pressure, or discharge in some cases
Treatment Approach
Conductive hearing loss is often treatable — through earwax removal, medication for infection, or in some cases minor surgery. When the underlying cause can't be fully corrected, hearing aids can effectively restore sound levels.
2. Mixed Hearing Loss
Mixed hearing loss is exactly what it sounds like — a combination of conductive and sensorineural hearing loss happening at the same time. There's a mechanical blockage in the outer/middle ear and some degree of inner-ear or nerve-related damage.
Common Causes
- A long-standing conductive issue (like chronic ear infections) alongside age-related inner-ear decline
- Head trauma affecting both the middle and inner ear
- Combined genetic and environmental factors
Typical Symptoms
- Sounds are both muffled and unclear, even when loud enough
- Difficulty understanding speech, especially in noisy settings
- Symptoms of both conductive and sensorineural loss together
Treatment Approach
Management usually addresses both components: treating the conductive part medically where possible, while fitting hearing aids to compensate for the permanent sensorineural component.
3. Sensorineural Hearing Loss
Sensorineural hearing loss (SNHL) is the most common type of permanent hearing loss. It happens when the tiny hair cells inside the cochlea (inner ear) or the auditory nerve itself are damaged, so sound signals aren't transmitted properly to the brain.
Common Causes
- Natural ageing (presbycusis)
- Prolonged exposure to loud noise
- Genetic or hereditary factors
- Certain illnesses, infections, or ototoxic medications
- Head injury or sudden acoustic trauma
Typical Symptoms
- Difficulty following conversations, especially with background noise
- Sounds seem unclear rather than simply quiet
- Struggling to hear high-pitched sounds like birds, doorbells, or children's voices
Treatment Approach
Sensorineural hearing loss is generally permanent and cannot be reversed with medication or surgery. It is effectively managed with properly fitted hearing aids, and in more severe cases, cochlear implants.
Comparison Table: Conductive vs Mixed vs Sensorineural
| Type | Where the Problem Occurs | Usually Treatable? | Common Management |
|---|---|---|---|
| Conductive | Outer or middle ear | Often, yes | Medical/surgical treatment, or hearing aids |
| Mixed | Outer/middle ear + inner ear/nerve | Partially | Treat conductive cause + hearing aids for the rest |
| Sensorineural | Inner ear (cochlea) or auditory nerve | Usually not reversible | Hearing aids or cochlear implants |
How We Diagnose Your Hearing Loss Type
You cannot reliably self-diagnose the type of hearing loss you have — the symptoms often overlap. Audiotone Hearing Clinics uses standard diagnostic audiometry (including air-conduction and bone-conduction testing) to pinpoint exactly where in your hearing pathway the issue lies, so we can recommend medical referral, hearing aids, or both.

Frequently Asked Questions
What are the 3 main types of hearing loss?
The three main types are Conductive Hearing Loss, Mixed Hearing Loss, and Sensorineural Hearing Loss. Each has different causes and is treated differently.
What is conductive hearing loss?
Conductive hearing loss happens when sound cannot pass efficiently through the outer or middle ear, often due to earwax buildup, fluid, infection, or a damaged eardrum. It is frequently treatable with medical or surgical care.
What is sensorineural hearing loss?
Sensorineural hearing loss occurs when the inner ear (cochlea) or auditory nerve is damaged, commonly due to ageing, noise exposure, or genetics. It is usually permanent and managed with hearing aids or cochlear implants.
What is mixed hearing loss?
Mixed hearing loss is a combination of conductive and sensorineural hearing loss, meaning problems exist in both the outer/middle ear and the inner ear or auditory nerve at the same time.
How do I know which type of hearing loss I have?
A diagnostic hearing test (audiometry) performed by a qualified audiologist is the only reliable way to identify the type and degree of your hearing loss. Book an assessment at Audiotone Hearing Clinics, Kukatpally.
Can hearing loss be treated?
Conductive hearing loss is often treatable medically or surgically. Sensorineural and mixed hearing loss are typically managed long-term with properly fitted hearing aids.
