Hearing plays an essential role in communication, speech and language development and learning. Even a small amount of hearing loss can have profound negative effects on speech, language comprehension, communication, classroom learning, and social development. Students indicate that without proper intervention, children with mild to moderate hearing loss, on average, do not perform as well in school as children with no hearing loss. This gap in academic achievement widens as students progress through school.
An estimates 12.5% of children and adolescents aged 6-19 years (approximately 5.2 million) and 17% of adults aged 20-69 (approximately 26 million) have suffered permanent damage to their hearing from excessive exposure to noise.
