A new University of Minnesota study finds relatively few of the young people diagnosed with hearing loss actually have it.
Conventional testing of the hearing of members of the U of M marching band indicated 15% of them had noice-induced hearing loss. But follow-up testing found the figure was closer to 5%. Study co-author Bert Schlauch says his research shows the estimated prevalence of hearing loss among young people is over-exaggerated. He cautions against complacency about children’s hearing, though. Schlauch says damage from loud sounds can build up over time and not appear until a person is older.
