In a study that sought to examine the current prevalence of hearing loss in US adolescents and determine whether it has changed over time, it was found that the prevalence of hearing loss among a sample of US adolescents aged 12 to 19 years was greater in 2005-2006 compared with 1988-1994. Hearing loss is a common sensory disorder, affecting tens of millions of individuals of all ages in the United States. In school-aged children, even slight hearing loss can create a need for speech therapy, auditory training, and special accommodations. Mild hearing loss in young children can impair speech and language development and lead to decreased educational achievement and impaired social-emotional development.
