  8. How We Hear

  9. 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

  10. 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)
