Unidentified hearing impairments in the school population are associated with speech and language delays, decreased attention span, and academic deficits. 5 Even mild hearing loss can significantly interfere with the reception of spoken language and education performance. Research indicates that children with unilateral hearing loss (in one ear) are ten times as likely to be held back at least one grade compared to children with normal hearing. 6 Chronic otitis media (OME), affects 5-30% of children aged 6 months to 11 years, and can persist for 4 to 5 months with or without medical intervention. 7 During this period, the child is at risk for a fluctuating hearing loss that can affect speech and language acquisition and auditory processing. 5 In school, students must be able to listen in a noisy environment, pay attention, concentrate, and interpret information. Reading success is particularly affected by the linguistic skill of interpreting information. Therefore, a child with a hearing loss is at a greater risk for academic deficits. Since hearing has such an impact on the ability to learn how to read, half of children with hearing loss graduate from high school with a 4th grade reading level or less unless appropriate early educational intervention occurs. 8 Hearing Loss due to Excessive Noise Exposure: Hearing loss can also be caused by an overexposure to noise. There is a growing occurrence of hearing loss in children and adolescents due to overexposure to noise; this is called noiseinduced hearing loss (NIHL). 9 Approximately 17 million Americans have NIHL even though it’s completely preventable. 10 Children are often exposed to excessive levels of sound; one study shows 97% of 3rd graders had been exposed to hazardous sound levels. 11 Sources of excessive noise for children include loud music, real or toy firearms, power tools, fireworks, loud toys, snowmobiles, and other loud engines such as jet skis, motorcycles or farm equipment. 11 A tenyear school district study showed the incidence of hearing loss increased 400% in eighth graders. 12 The significance of the problem lies in the insidious nature of noise-induced hearing loss as well as the cumulative interaction between this type of loss and the natural aging process that affects hearing. Addressing hearing loss early and taking steps to prevent it is vital. Depending on the amount of exposure to noise, the effects of hearing loss may come on very gradually, and hearing loss as a result of damage to hair cells is permanent. 13 2
