Types of Hearing Loss and Corresponding Audiograms
Hearing loss can occur when there is a problem affecting the outer ear, middle ear, inner ear or the pathways that carry sound signals to the brain.
The type and location of the problem can influence how sound is affected. An audiological assessment helps identify the nature and severity of hearing loss and provides important information when considering appropriate treatment or support.
Outer Ear
Collects and directs sound.
Middle Ear
Transfers sound vibrations.
Inner Ear
Converts sound into nerve signals.
There Are Three Main Types of Hearing Loss.
Select a type below to learn more about how it affects hearing and to view its corresponding audiogram.
Conductive Hearing Loss
Sound is prevented from travelling efficiently through the outer or middle ear.
Sensorineural Hearing Loss
Hearing is affected by changes involving the inner ear or auditory nerve pathways.
Mixed Hearing Loss
A combination of conductive and sensorineural hearing loss can occur.
Conductive Hearing Loss
Conductive hearing loss occurs when sound is unable to travel efficiently through the outer ear or middle ear towards the inner ear.
Depending on the cause, this type of hearing loss may affect the loudness and clarity of sounds.
- Can involve the outer ear
- Can involve the middle ear
- May affect sound transmission
- Audiological assessment helps identify the cause
Sensorineural Hearing Loss
Sensorineural hearing loss involves the inner ear or the pathways that carry sound information towards the brain.
It can affect how sounds are heard and how easily speech is understood, particularly in more challenging listening environments.
- Can involve the inner ear
- Can involve auditory nerve pathways
- May affect speech understanding
- Professional testing identifies the hearing profile
Mixed Hearing Loss
Mixed hearing loss refers to a combination of conductive and sensorineural hearing loss.
This means that there may be a problem affecting both the transmission of sound through the outer or middle ear and the functioning of the inner ear or auditory pathways.
- Includes conductive components
- Includes sensorineural components
- Requires a detailed hearing assessment
- Treatment depends on the individual cause and needs
Your hearing is unique.
A professional audiological assessment can help identify the type and degree of hearing loss and provide guidance on the most appropriate next steps.
