Presbycusis is a form of hearing loss that is associated with aging. Repeated exposure to loud sounds such as traffic or loud music can cause this type of hearing loss as well. Presbycusis is caused by changes in the inner ear or auditory nerve. The most common reason for the cause of presbycusis is from the loss of hair cells in the inner ear. Presbycusis can also be caused by changes in the blood supply to the ear from heart disease or high blood pressure. In order to avoid loss of hearing prevention should be taken when exposed to loud noises such as wearing ear plugs or with special fluid-filled ear muffs. Hearing aids may be recommended for people suffering from presbycusis that will help provide improvement for the individual to hear better.
