A recent study examined hearing loss data for 1613 U. S. teenagers. In this sample, 325 were found to have some level of hearing loss. News of this study spread quickly, with many news articles blaming the prevalence of hearing loss on the higher use of ear buds by teens. At MSNBC. com (8/17/2010), Carla Johnson summarized the study with the headline: "1 in 5 U. S. teens has hearing loss, study says."
