ScienceDaily.com reported a recent study showing secondhand smoke caused hearing loss in teens. The study looked at 1500, 12-19 year olds for nicotine and hearing loss. They found those exposed to the secondhand smoke were twice as likely to have hearing loss then those who were not exposed. The more secondhand smoke the teens were exposed to the greater the risk for hearing loss.
They found hearing was affected in the mid to high frequency range interfering with the ability to understand words and speech. This caused words to be misheard. In a classroom the teens can mishear teachers resulting in misunderstanding information and assignments, ultimately affecting school performance.
Hearing loss among teens and children is on the rise. Secondhand smoke is not the only cause. Teens are also at risk for noise induced hearing loss. 12.5% of 6-19 year olds have documented hearing loss related to noise exposure. Learn more about hearing loss at: http://aacHEAR.org/education
Teens with undiagnosed and untreated hearing loss often have socialization problems. They can have difficulty in social situations, lack self confidence and have low self esteem. Also, teens who cannot hear well in the classroom get bored, act out and become labeled troublemakers or labeled as ADHD.
Typically misheard words and speech are blamed on the speaker. Rarely does one realize hearing is the culprit. If your child or teen misunderstands words or information, schedule an appointment with an audiologist for a hearing evaluation.
