1 - How Hearing Works

Types of hearing loss

There are four types of hearing loss:
  • Sensorineural. Results from abnormalities in the hair cells.
  • Conductive. Results from abnormalities in the structure of the ear. This type of hearing loss can also result from fluid buildup in the middle ear, which may be reversible.
  • Mixed. Includes features of both sensorineural and conductive hearing loss.
  • Auditory neuropathy. Caused by a disruption in the transmission of sound from the inner ear to the brain, though its cause is not completely understood.
