Description
With all the noise around us, is our hearing really in danger? Dr. Know (Paul Trotman) enlists an audiologist to test sound levels around the home and at a heavy metal concert. He also tests out a variety of hearing protection to see which kind was most effective to prevent hearing loss due to loud noises. This DVD is geared more towards adolescents in grades 6-12 as a teaching tool about hearing.
