Types of hearing loss
Hearing problems can be mild, moderate, severe, or profound. Most people classified with ‘deafness’ have profound hearing loss, which implies very little or no hearing. It is possible to develop loss of hearing in one ear, although it usually affects both ears. Depending on the cause, hearing impairment can be mild or severe, temporary or permanent. Sudden hearing loss typically results from a loud noise event.
Physically, there are two types of hearing loss: sensorineural hearing loss and conductive hearing loss.
