Researchers at the Universtity of Giessen in Germany spent over a decade testing the hearing of some 10,000 people. As expected, people exposed to very loud noises as part of their jobs, such as construction workers, had poor hearing. But those living in quiet rural areas had hearing not much better. And people, including airline pilots or orchestral musicians, who encoutner constant noise at work, could hear very well. Firefighters, whose lives can depened on sounds, had exceptional hearing.
