How We Hear
Deaf & Hearing Awareness Training
Conductive Hearing Loss
• This is when sound cannot be conducted (pass through) the outer and middle ear.
The causes include: • collection of fluid in the middle ear ('glue
ear' in children)• damage to the eardrum by infection or
trauma• blockage of the outer ear (by wax)• middle ear infections
Deaf & Hearing Awareness Training
Sensorineural Hearing Loss
This happens when the tiny hair cells in the cochlea are damaged and so do not convert sound into electrical impulses.
The causes include:• age related hearing loss (a natural part of the
aging process)• acoustic trauma (such as a loud noise) to the
hair cells• viral infections of the inner ear (measles,
mumps, chickenpox)
