Ear sonovive can be caused by a variety of factors. Exposure to loud noise is a big cause. Lots of people with this condition got it right after they were at a concert, where they had a front seat. (And paid lots of money for it, too.) Exposure to frequent, loud noise from heavy machinery has also been shown to cause sonovive .
Another common cause of sonovive is as you get older, the nerve endings in the ear tend to get more and more damaged, which could cause you to develop sonovive at an older age.
