Conductive hearing loss occurs when sound is blocked from the outer ear to the inner ear. A person experiences loss of volume, often hearing faint sounds. Conductive hearing loss can usually be improved through medical or surgical intervention.
Common causes of conductive hearing loss include:
* Build-up of ear wax
* Foreign object in the ear
* Middle ear infection 'glue ear'
* Malformation on the outer ear, inner ear, ear canal or middle ear
* Punctured ear drum
Hearing loss which happens when there is damage to the inner ear, auditory nerve or the brain is referred to as sensorineural. People with sensorineural hearing loss experience a reduction in the volume and clarity of sound.
This type of hearing loss is caused by many factors. Damage to the ears can be related to ageing, exposure to loud noise, infection, illness, medications, heredity and head injury.
A person can also have mixed hearing loss, a combination of sensorineural and conductive hearing loss.
If you, or a person in your care, are displaying any signs of hearing loss or clarity of hearing it is advisable to consult a medical practitioner as soon as possible. |
