Injury and hearing

The middle and inner ears are protected by the temporal bones, located at the base and sides of the skull. Head injury that involves trauma to the temporal bones can cause hearing loss. Concussion may be enough to cause hearing damage, even if the skull bones arent broken.Otitic barotrauma refers to hearing damage caused by changes in air pressure on either side of the eardrum. This can be caused by descending or ascending through water too quickly for example, while scuba diving.
