Hearing aid - Definition


A hearing aid is a medical device intended to re-establish a satisfactory auditive acuity. The auditive apparatus must be prescribed by a doctor after the assessment of an auditive loss. The hearing aid can be inserted in the auditory canal or wrap around the external portion of the ear, or both. A hearing aid may need adjustment to achieve the right sound volume, and the wearer may need speech therapy, especially in cases of long-term deafness.
