Increase in Hearing Loss in Adolescents Courtesy of Coastal Ear, Nose & Throat

During the holiday season, you are probably overwhelmed with determining what gift to get for your teenage family members. How about preserving their hearing? The number of adolescent children with a slight hearing loss has significantly increased in recent years. Even a slight degree of hearing loss can result in more difficulty with understanding speech in a classroom setting.

The Journal of the American Medical Association published an article in August 2010 regarding the prevalence of hearing loss in children age 12-19 years in the United States. The researchers compared data from the Third National Health and Nutrition Examination Survey regarding the hearing sensitivity of teenagers in the 1988-1994 timeframe to 2005-2006. There was a significant increase in the prevalence of a slight hearing loss in this age group, rising from 14.9% in 1988-1994 to 19.5% in 2005-2006. Hearing loss has become more commonly unilateral (only present in one ear) and tends to primarily affect the high frequencies in teenagers today.

There is speculation that the recent increase in hearing loss in teenagers may related to the increased use of personal music devices by this age group. If you can hear the music coming from someone’s ear buds or headphones, the volume is set too high. Noise cancelling headphones instead of ear buds may be considered to allow for MP3 players and IPODs to be enjoyed at a lower volume setting. Repeated exposure to noise at a dangerously loud level can result in a permanent hearing loss. Portnuff and Fligor (2006) evaluated the safe listening volumes over time for several portable music players. They recommended that the volume may be set at 70% for no more than 4.6 hours of use per day in order to avoid a permanent noise-induced hearing loss. Higher volume levels put children at a higher risk for permanent damage to their hearing – for example, 80% volume setting should not be used for more than 1.2 hours at a time. There are now ways that parents can limit the maximum volume levels on the IPOD to prevent children from listening at a potentially harmful level.
